Eaton SPD Series
surge protective device for integrated applications
1.0 Introduction
1.1 Manual organization
This installation manual describes the safe installation, testing
and operation of the Eaton®SPD Series surge protective device
(SPD).
1.2 Product overview
The Eaton SPD Series protects critical electrical and electronic
equipment from damage by power surges. This is done by
shunting high energy lightning surges (and other transient
disturbances) away from the equipment being protected. It does
this in nanoseconds by providing a low impedance surge path to
ground while supporting power frequency voltage.
The Eaton SPD Series is designed to mount on panelboards,
switchgear, switchboards, busway, and motor control centers
(MCCs). It is available with surge current capacity ratings from
50 to 400kA.
The Eaton SPD Series is available in four feature packages
(Basic, Standard, Standard with Surge Counter, and Power Xpert
SPD), as described in Section 3, "Operating features." Each
model is available in delta, high leg delta, wye, single phase and
split phase wiring configurations.
All Eaton SPD Series models have been tested and certified
by Underwriter’s Laboratory (UL®), to comply with UL 1449, 4th
edition.
Eaton’s One-Port low-voltage surge protective device wye
models SPD120480Y2C, SPD160480Y2C, SPD200480Y2C
and Delta Models SPD120480D2C, SPD160480D2C,
SPD200480D2C meet the requirements of IEC 61643-11 / EN
61643-11, part 11: test class II, and are intended to be installed
in indoor applications with a degree of protection rated IP 00.

Each Eaton SPD Series unit has a name plate that identifies
the parameters used for manufacture. These parameters are
expressed in letters and numbers to reflect the series, kA
rating, voltage code, feature package, and application.
Table 1. Catalog numbering system
SPD 250 480D 2 J
For example, a 480 volt delta (3-wire plus ground) for use in
an MCC application requires an SPD model SPD 250480D2J,
where:
SPD = SPD model,
250 = the kA rating (50 – 400 kA),
480D = the voltage,
2 = the feature package (Basic, Standard, Standard with Surge
Counter, or Power Xpert SPD),
J = the application suffix (such as direct bus mounted in a
panelboard or connected through a circuit breaker).
These numbers also appear as part of the product label attached
to the front left side of the SPD. See Figure 1.

1.5 Equipment testing
WARNING
CONDUCTING DIELECTRIC, MEGGER, OR HI-POTENTIAL TESTING
WITH THE SPD INSTALLED WILL CAUSE INTERNAL DAMAGE TO THE
SPD. THE SPD WILL ALSO CAUSE THE TEST TO FAIL.
Every Eaton SPD Series unit is tested at the factory for dielec-
tric breakdown. No further SPD testing is required for installa-
tion.
If you desire to test distribution equipment by performing
dielectric, megger, or hi-potential tests, any installed SPD must
be disconnected from the power distribution system to prevent
damage to the unit.
Follow this procedure to safely disconnect the SPD:
1. Remove bus connected SPDs completely from the
installation prior to performing any form of hi-potential
testing.
2. Isolate SPDs connected via conductors as follows:
a. 3-wire delta SPDs: Turn off the circuit breaker to
isolate the SPD, if connected through a circuit breaker.
b. Wye connected SPDs: Turn off the circuit breaker and
remove the neutral connection.
3. Remove MCC units with SPDs from the MCC structure.

4. Determine the wire length required to connect to the
breaker and cut phase wires to the appropriate length. (To
maximize SPD performance, wire length should be as short
as possible).
ote:N For wire lengths longer than 4", phase wires should
be twisted once for each 4" of wire length to maximize SPD
performance.
5. Connect phase wire to circuit breaker. NEC requires that
conductors to a surge device be protected by an overcurrent
protection device. The cables on the SPD are #10 AWG,
therefore would require a 30A 3-pole breaker. See Figure 15,
and the wiring diagrams shown in Figures 6, 7, 8, 9 and 10.
Figure 15. Phase connections
6. Connect the system ground wire (green) to the SPD’s surge
ground connection using a ring terminal suitable for use
with a #10 fastener and #10-32 x 3/8" fastener (customer
supplied). Tighten the surge ground connection to 4.1 N∙m
(36 in-lbs). If the system uses an isolated ground, connect
the isolated ground wire to surge ground. There are two
surge ground connection points provided on the SPD.
Connect only one of them. See Figure 11.
7. If equipped, connect the system neutral wire (grey or white)
to the SPD. Connect the system neutral wire to the SPD’s
neutral connection using a ring terminal suit able for use
with a #10 fastener and a #10-32 x 3/8” fastener (customer
supplied). Tighten the neutral connection to 4.1 N∙m
(36 in-lbs). There are two neutral connection points provided
on the SPD. Connect only one of them. See Figure 12.
8. The SPD (Standard, Standard with Surge Counter and Power
Xpert models) also have a connection available for remote
monitoring of the form C relay contacts. See Figure 13. This
is a green connector located on the side of the SPD. To make
the connection, remove the green connector and install
the remote monitor leads (connector supports 12-24 AWG
wire). Fasten the remote monitoring wires to the N.O.,
N.C. and COM connection points per the label on the front
of the SPD. Contacts are rated: 150 Vac at 0.46A, 30Vdc at
1A. Follow all national, state and local electrical codes. With
wiring complete, plug the green connector into the SPD.
9. The final step of the SPD installation depends on the specific
application. The various applications are listed below by
catalog suffix.
a. Suffix 'B': This is the remote display panel (RDP) option.

3.0 Operating features
3.1 General
The Eaton SPD Series comes in four feature packages: Basic,
Standard, Standard with Surge Counter, and Power Xpert SPD.
The operating specifics of each feature package are described
below.
The Eaton SPD Series requires no operator involvement, other
than to monitor the display panel to determine status of the
SPD.
After system power is applied, the SPD automatically begins
protecting downstream electrical equipment from voltage tran-
sients.
Some SPD units have a form C relay contact that allows for
the remote indication of SPD status. Form C contact wires are
connected via a three terminal connector. See Figure 13.
3.2 Displays and indicators
All of the Eaton SPD Series units (Basic, Standard, Standard
with Surge Counter, and Power Xpert SPD) use a display panel
to indicate system status. The display panel is slightly different
for each feature package.
The display in features 1, 2 and 3 have both green and red light
emitting diodes (LEDs) to indicate the status of protection on
each phase. Green indicates the phase is fully protected. Red
indicates a loss of protection. Wye, split phase and high-leg
delta units have an additional set of green/red LEDs to indicate
status of neutral/ground protection.
The display in feature 4 has green, yellow and red illuminating
LEDs to indicate the status of protection in phases A, B and C.
Systems with a neutral wire will show the status of protection in
N-G mode.
When an LED turns red, an audible alarm will sound on units
equipped with an audible alarm.
For features 1, 2 and 3 push the alarm silence button to silence
the alarm. For the Power Xpert SPD push any of the four push-
buttons on the display to silence the alarm.
Specific operating conditions displayed for each Eaton SPD
Series feature package are described below.
3.2.1 Basic feature package
The Basic feature package has the following features:
• Green LEDs: Illumination indicates the phase is fully
protected, and operating normally, with all protection active
and available. Green LEDs also indicate neutral to ground
protection on units with a neutral wire. Green LEDs do not
indicate on/off status of power.
• Red LEDs: Illumination indicates a loss of protection, and that
one or more protective devices are now inactive and unavail-
able for that phase. Red LEDs also indicate neutral to ground
protection on units with a neutral wire. Red LEDs do not
indicate on/off status of power.
