1 Introduction
1.1 General
The SB6100 Industrial Shock Block®is available as a
ground-fault circuit interrupter (GFCI), special-purpose
ground-fault circuit interrupter (SPGFCI), or as an
equipment ground-fault protective device (EGFPD). All
types operate within the time-current curve defined by UL
943 and CSA C22.1 for Class A GFCIs.
The SB6100 is available in open-chassis or enclosed
models for voltages from 208 to 600 V. All SB6100
models are continuously rated at 100 A and include
overcurrent protection through Littelfuse Class T fuses.
Enclosed models have a NEMA-4X rating and are UL-
listed. The open-chassis models are UL-recognized for
installation by an original equipment manufacturer.
The following model types are available:
•GFCI Class A with a 6 mA fixed trip level
•SPGFCI Class C with a 20 mA fixed trip level
•SPGFCI Class D with a 20 mA fixed trip level
•EGFPD with selectable trip-level settings from 6
to 100 mA
Class A GFCIs are UL 943 listed (enclosed) or UL 943
recognized (open chassis).
Class C and Class D SPGFCIs are UL 943C listed
(enclosed) or UL 943C recognized (open chassis).
EGFPD models have adjustable trip-level settings from
6 to 100 mA, and are UL 943 and UL 1053 listed
(enclosed), or UL 943 and UL 1053 recognized (open
chassis). All models except for Class A GFCIs are
certified by CSA to C22.2 No. 144-M91.
Each SB6100 includes an AC6000-OPI-00 Operator
Interface with status-indication LEDs and control buttons.
SB6100s are rated for use as a motor controller.
1.1.1 SB6100 GFCI
GFCI models are permanently-connected GFCIs that
meet the requirements of the UL 943 definition for Class
A devices, with a fixed 6-mA trip level. It is available
only for 208 Vac systems.
1.1.2 SB6100 SPGFCI
SPGFCI models are permanently-connected special-
purpose GFCIs that meet the requirements of UL 943C
definitions for Class C and Class D devices, with a fixed
20-mA trip level. These classes extend GFCI protection
beyond the standard 6-mA Class-A GFCI and are
appropriate for many industrial and commercial
applications.
Special-purpose SB6100 GFCIs (Class C or Class D)
can be used in the following applications:
•3-Phase Grounded-neutral systems where voltage to
ground is above 150 Vac and equipment grounding or
double insulation is required by the National Electrical
Code (NEC) and ANSI/NFPA 70.
•3-Phase Grounded-neutral systems where voltage to
ground is 150 Vac or less and equipment grounding or
double insulation is provided, but the use of a Class A
ground-fault circuit interrupter is not practical.
•Any 3-Phase CEC application in which a Class A
GFCI is not required.
The UL GFCI classes and their intended applications
are shown in Fig. 1.
The SB6100 also provides ground-connection
monitoring as required by UL 943C. The ground-
monitoring function automatically disconnects the supply
if the load is not properly bonded to ground, and requires
a cable pilot wire and a termination device installed at the
load. The SB6100 will not allow its contactor to close on
power-up and will open the contactor if the load ground is
not connected.See Fig. 2.
If required by the application, a load-ground-
connection monitor feature can be enabled for Class A
GFCI models. See Section 2.5.
FIGURE 1. UL GFCI Classes.

SB6100 Industrial Shock Block Page 2
Rev. 1-I-071520
1.1.3SB6100 EGFPD
EGFPD models can be set to trip at
6 mA or from 10 to 100 mA in increments of 10 mA, and
meet the requirements of UL 943 and
UL 1053. All EGFPD models are certified by CSA to
C22.2 No. 144-M91.The adjustable trip level can help
prevent nuisance tripping in some applications.
If required by the application, a load-ground-
connection monitor feature can be enabled for EGFPD
models. See Section 2.5.
1.2 Features
•UL 943 inverse time curve reduces the probability of
nuisance tripping.
•UL 943 fixed trip level (Class A GFCI models)
provides protection meeting NEC 210.8 (B) for
commercial kitchens, wet areas, and other
applications.
•UL 943C fixed trip level (GFCI models) provides
protection for systems with leakage current higher
than the 6-mA trip level required by Class A GFCIs.
•Selectable trip levels (EGFPD models) help reduce
nuisance tripping by allowing users to adjust the trip
level in systems that have leakage current higher than
UL 943 Class A 6-mA trip level, or UL 943C Class C
or D 20-mA trip level.
•UL 943C ground-connection monitoring ensures
continuity of the load ground.
•Undervoltage, brown-out and chatter detection
prolong the internal contactor lifetime.
•Overcurrent protection is provided with three
200 A, 600 V Class T fuses.
•Can be used as a motor or pump starter.
•Meets UL 1998 requirements.
•Self-test feature continuously monitors hardware to
ensure safe operation.

•LED status indication
•Power (PWR) and Enabled (EN) indicators
•Ground Leakage indicators (25%, 50%, 75%, and
100%)
•Fault (FLT), Input Connection (INP), and Load
Ground Connection (GC) indicators
•Test/Stop and Reset/Start buttons
2. Installation
The SB6100 is considered to be a permanently mounted
GFCI/EGFPD and should be attached to a wall or other
suitable mounting surface.
The connection diagram for three-phase systems is
shown in Fig. 2. Ensure that all conductors have the
required voltage and current ratings necessary for the
application. SB6100 installation should be performed by
a qualified person.
2.1 Mounting
2.1.1 Open-Chassis Models (SB6100-XX0-0)
Open-chassis models are to be mounted in a suitable
enclosure for the intended environment. Follow the IP or
NEMA guidelines for the required enclosure type. Install
in the correct orientation as shown in Fig. 4, and refer to
the ‘This Side Up’ label attached to the side of the chassis.
Open-chassis models include an Operator Interface
(AC6000-OPI-00) and 3 m of cable.
The AC6000-OPI-00 should be mounted from the back
side of a panel. Prepare a mounting cut-out as shown in
Fig. 6. For a water-resistant installation, ensure that the
supplied gasket makes suitable contact with the panel.
Secure with eight 4-40 machine screws and hex nuts. If it
is desired to have a flush install, use flat-head machine
screws and countersink the holes as shown in Fig. 6.
Attach the supplied cable to the SB6100 15-pin connector
labeled OPI, securing with the supplied screws, and to the
AC6000-OPI-00, ensuring that the connector locks into
place. Secure the cable with cable ties.
2.1.2 Enclosed Models (SB6100-XX1-0)
Install enclosed models in the correct orientation as
shown in Fig. 5, and refer to the ‘This Side Up’ label
attached to the side of the enclosure.
Enclosed models ship with no cable entry points
predrilled. An appropriate hole or holes must be made in
the enclosure and fitted with NEMA-4X-rated fittings for
the installation of all conductors. Space is left near the
bottom of the enclosure to install the wiring. See Figs. 3
and 8.
2.2 Supply Connections
The supply phases are marked Input 1, 2, and 3 on the
base of the chassis as shown in Fig. 3. Use a 5/16” hex
(Allen) key to tighten the input connections. Torque the
input terminals as described in Section 7. The input
terminals will accept 14 to 2/0 AWG (2.08 to 67.4 mm2)
conductors.
2.3 Load Phase Connections
The load phases are marked Output 1, 2, and 3 on the
base of the chassis as shown in Fig. 3. Use a 3/16” hex
(Allen) key to tighten the output connections. Torque the
output terminals as described in Section 7. The output
terminals will accept 14 to 2/0 AWG (2.08 to
67.4 mm2) conductors.

SB6100 Industrial Shock Block Page 3
Rev. 1-I-071520
2.4 Ground Connections
Connect the supply and load ground conductors to the
chassis bonding point ( ) as shown in Fig. 3. Use a flat-
blade screwdriver to tighten the ground connections.
Torque the ground terminals as described in Section 7.
The ground terminals will accept 14 to 1/0 AWG (2.08 to
53.5 mm2) conductors.
2.5 Load-Ground-Connection Monitor
An insulated pilot wire from the SB6100 to the load,
and a termination device located at the load are required
to monitor the load-ground connection. Total pilot wire
and ground wire resistance must be less than 38 ohms.
Outline dimensions and mounting details for compatible
termination devices are shown in Figs. 9, 10, and 11.
This monitoring function is required for Class C and
Class D GFCI models installed in NEC applications, and
can be implemented if desired for Class A GFCI or
EGFPD models.
Use only a Littelfuse termination device as others may
not meet performance requirements. Each SB6100 GFCI
is supplied with a 1N5339B termination device. Install
the termination device at the load to complete the ground-
connection loop as shown in Fig. 2. Connect terminal G
of the termination device to the equipment frame so that
the ground-conductor-to-equipment-frame connection
will be included in the monitored loop. Connect terminal
GC to the pilot wire and connect the pilot wire to the
SB6100 terminal GC as shown in Figs. 2 and 3.
EGFPD models include a 1N5339B termination device
installed at the GC terminal. The termination device
should remain installed at the GC terminal if the load-
ground-connection monitoring feature is not required.
2.6 Auxiliary Contactor Terminals
An auxiliary normally-open contact (labeled AUX) is
provided on all models. This contact, rated at 4 A,
240 Vac, follows the state of the internal contactor. See
Figs. 2 and 3.

3. Operation and Setup
NOTE: When its input terminals become energized,
the SB6100 powers up in RESET/START mode
and the connected circuit will be energized after a brief
system test.
The operator interface (AC6000-OPI-00) provides
indication and control for the SB6100. The
AC6000-OPI-00 has nine LEDs and two buttons
(TEST/STOP and RESET/START). The LEDs indicate
power (PWR), output state (EN), ground leakage (25%,
50%, 75%, and 100%), and trip status (FLT, INP, and
GC). See Figs. 6 and 7.
3.1 Operator Interface (AC6000-OPI-00) Buttons
3.1.1 Test/Stop
The TEST/STOP button is used to de-energize the load
and to test the SB6100 ground-fault detection circuit,
indication, and contactor. When the TEST/STOP button
is pressed for one second, all four Ground Leakage LEDs
and the FLT LED will turn ON, the EN LED will turn
OFF, and the SB6100 will trip.
3.1.2 Reset/Start
The RESET/START button is used to reset the SB6100
after a ground fault has occurred and to energize the load.
When the RESET/START button is momentarily pressed
and there are no fault conditions present, the contactor will
close and the enable (EN) LED will be ON. If the SB6100
trips immediately after a reset, a ground fault is still
present.
3.2 Operator Interface LED Indication
3.2.1 Power
The green LED labeled PWR indicates the presence of
supply voltage.
3.2.2 Enabled
The green LED labeled EN indicates that the contactor
is closed. An audible sound from the internal contactor
can be heard each time the contactor opens or closes.
When supply voltage is applied to the SB6100, the
SB6100 closes the contactor after a three-second delay, if
there are no fault conditions present.
3.2.3 Ground Leakage
The four yellow GROUND LEAKAGE LEDs indicate
the presence of ground-leakage current at 25, 50, 75 and
100% of the trip level. For an EGFPD, the trip level can
be selected from 6 to 100 mA. For a GFCI, the trip level
is fixed at 6 mA (Class A) or 20 mA (Class C and D).
Table 1 describes the operation of the ground-leakage
LEDs.

3.2.4 Trip
Three red trip LEDs provide detailed trip indication.
If the FLT LED is on, the unit has tripped. One or more
conditions may have caused a trip. If the FLT LED is
flashing, the SB6100 has detected a brown-out or
chattering condition. See Table 2 and Sections 3.5 and
3.6.
If the INP LED is on, the supply wiring is not connected
properly. See Section 3.4. If the INP LED is flashing, the
SB6100 has detected a supply undervoltage condition.
See Table 2 and Section 3.5.
If the GC LED is on, the load ground is not connected.

3.3 Settings
The GFCI models have a fixed 6 mA (Class A) or 20
mA (Class C and D) trip-level value.
The EGFPD models can be set to trip at 6 mA, or from
10 to 100 mA in increments of 10 mA. The TRIP LEVEL
(mA) rotary selection switch is located on the chassis front
panel. See Figs. 3 and 4.
3.4 Input Connection
The input supply connection is checked for correct
wiring during power-up. The red Input Connection (INP)
LED will be on and the SB6100 will not close the

SB6100 Industrial Shock Block Page 12
Rev. 1-I-071520
contactor if any of the following conditions are present:
•Input 3 is not connected
•Input 3 fuse is open
•Supply ground is open
After the SB6100 input supply connection is corrected,
the SB6100 will automatically close the contactor if no
other fault conditions are detected.
NOTE:SB6100 electronics are supplied from input
phases 1 and 2. If either phase is not connected, the unit
will remain off with the contactor open.
NOTE: The input connection is checked for correct
wiring only during power-up. Accordingly, if Input 3 or
the supply ground opens during normal operation, the
SB6100 will not detect an input supply connection
problem.
3.5 Undervoltage and Chatter Detection
The input voltage is always checked before the
contactor is closed. If an input undervoltage condition is
detected, the contactor will remain open and the red INP
LED will flash every second. The control circuit will
continuously check the input voltage and will close the
contactor when the input voltage is within acceptable
limits.
Undervoltage detection is provided to prolong the
lifetime of the contactor by preventing contactor chatter.
Contactor chatter occurs when the voltage applied to the
control coil is marginally lower than the minimum pull-in
voltage.
3.6 Contactor Monitoring
The SB6100 continuously monitors the state of the
contactor. If an incorrect state is detected, the FLT LED
will flash every second, the contactor will open and will
remain open until supply voltage to the unit is cycled.
This condition should never be encountered during normal
operation.
The SB6100 should be used within the specifications
listed in Section 7 to ensure correct operation.
NOTE: At room temperature, the minimum contactor
pull-in voltage is approximately 80% of the nominal
voltage. At higher temperatures, the minimum pull-in
voltage is higher than 80% of the nominal voltage.
3.7 Ground-Fault Detection
The red Fault (FLT) LED indicates a ground-fault trip.
The SB6100 will remain tripped until the RESET/START
button is pressed or supply voltage is cycled. See Section
3.1.2.
3.8 Momentary Power Loss and Brown-Out
Detection
When supply voltage to the SB6100 is removed, the
contactor will open and the green PWR and EN LEDs will
turn off. For a short supply outage of approximately 20
seconds, the SB6100 will remain powered-up and retain
its state prior to the outage (either energized or tripped).
For longer supply outages, the SB6100 will power-up in
an untripped state.
In the case of a brown-out condition where the input
voltage dips too low, the contactor will open, and the red
FLT LED will flash every second. The SB6100 will
remain in a tripped state until RESET/START is pressed.
Before pressing RESET/START, ensure the input voltage
is within the acceptable range.
NOTE:At 25°C (77°F), the contactor drop-out voltage
level is approximately 60% of the nominal supply voltage.
At higher temperatures, the contactor drop-out voltage is
higher than 60% of the nominal voltage.
3.9 Load-Ground-Connection Monitor
The Load-Ground-Connection Monitor (GC) LED
indicates that the load ground is open. If the load ground
connection is not connected during power-up or becomes
disconnected during normal operation, the GC LED will
turn ON and the contactor will open.
The SB6100 continuously monitors the load ground
and will automatically close the contactor if the load-
ground connection is restored.
NOTE:Load-ground-connection monitoring is only
required for GFCI Class C and Class D models as per UL
943C. Refer to Section 4.3 for a description of the UL
943C load-ground monitor requirements. For EGFPD and
GFCI Class A models, load-ground-connection
monitoring is optional.
3.10 UL 943 Self-Test and UL 1998 Requirements
The 2015 revision to the UL 943 standard includes a
self-test requirement to verify a GFCIs ability to respond
to a ground fault. All SB6100 options (revision 01 or
newer) include an automatic self-test feature. If a problem
is detected, the SB6100 will trip. A Self-Test Failure will
be indicated by a unique LED pattern as shown in Fig. 12.
A self-test is initiated a few seconds after power-up, a
few seconds after the contactor is closed, and hourly
during normal operation. A self-test may be indicated by
a brief flash of one or several ground-leakage LEDs.
In addition to the automatic self-test, a monthly manual
test is also recommended.
Compliance to the UL 1998 Software in Programmable
Components standard is also included.

SB6100 Industrial Shock Block Page 13
Rev. 1-I-071520
FIGURE 13. SB6100 Temperature Derating Curve.
4. UL 943C Requirements
The following sections contain excerpts from the
UL 943C(1) Standard for Class C and D applications. For
EGFPD models, only Section 4.1 applies where selectable
trip levels from 6 to 100 mA are permitted
(20 mA is the only allowed trip level for GFCI devices in
NEC applications).
4.1 Trip Time
Class C and Class D GFCIs shall be capable of
interrupting the electric circuit to the load when the fault
current to ground (I) is within the range of a minimum of
20 mA through a maximum of (110% of the rated
voltage/500 Ω) A within the time interval (T) in
accordance with the relationship:
Where:
T is expressed in seconds, and
I is expressed in mA
Except that T is not required to be less than 20 ms.
The tripping threshold of these GFCIs shall be in the
range of 15 to 20 mA.
Fig. 14 shows the Class-A GFCI maximum-trip-time-
versus-current curve defined by UL 943 (with the above
formula); UL 943 also defines a limit to the formula, with
a minimum required trip time (or fastest trip speed) of
20 ms, which occurs at about 300 mA of ground-fault
current (I) per the formula. Class C and D GFCIs must
operate within this same curve, except that their operating
threshold is 15 to 20 mA (non-adjustable). See Fig. 15.
The SB6100 EFGPDs described in this manual also
operate within the Class-A formula, but have a 6- to
100-mA threshold setting range.
4.2 Grounding Circuit
The equipment grounding circuit of the circuit shall be
sufficiently low impedance that, should a fault to ground
occur, the voltage resulting across the grounding circuit
shall not exceed 150 V. The size of the grounding
conductor required for a circuit shall be determined by
calculating the resistance using the following formula and
converting that value to a wire gauge based on the length
of the equipment grounding conductor:
Where:
RGis the resistance of the equipment grounding
conductor
RUis the resistance of the ungrounded conductor, and
VLG is the RMS value of the supply line to ground
voltage
Refer to UL 943C Appendix A for a sample calculation
of grounding conductor size.

NOTES(4):
(1) The INP LED is shared between the miswire and undervoltage conditions. Miswiring has priority over undervoltage, i.e. if
both conditions occur at the same time the INP LED will stay on, indicating a miswire until the connection is fixed, then it will
flash if the undervoltage condition still exists.
(2) Supply miswiring test is only performed on power-up.
(3) The unit will pull in once the condition is corrected.
(4) It is possible for two of the above conditions to occur simultaneously. In this case each respective LED will individually indicate
one condition.
(5) Hardware revision 01 or newer.
6. Accessories
The AC6000-CART-00 two-wheeled cart is available
for enclosed models of the SB6100. The cart allows the
SB6100 to be moved when not powered, and supports up
to 23 kg (50 lb) of cable around the frame. The lower
panel size is 457 mm (18 in.) x 279 mm (11 in.) and can
be used as a mounting location for connectors or other
accessories. See Fig. 16 and Section 7.
The AC6000-MNT-00 mounting frame is available
separately. The mounting frame is shipped unassembled
and includes U-bolts to fit metal tubing with a 25 mm (1
in.) diameter. Alternate hardware (not supplied) can be
used to install the mounting frame to a user-supplied cart
or a wall. The frame supports up to 23 kg (50 lb) of cable
around the frame. See Fig. 17 and Section 7.
