Product Overview
The overcurrent control is programmed using a personal computer connected to the
control via a USB cable. The control features a variety of time-current characteristic
(TCC) curves and denite time settings listed in the "Overcurrent Control Settings" section
starting on page 47. Each overcurrent control can control up to two fault interrupters.
Current transformers are integral to the switchgear. These current transformers pro-
vide primary current sensing for the switchgear. The overcurrent control is capable of
sensing and responding to phase overcurrents, ground overcurrents, negative sequence,
and sensitive earth faults.
The power derived from the current transformers is used to operate the control and
to charge the trip capacitors that discharge into magnetic latching solenoids to trip
the fault interrupters during a fault. No external power is required for operation of the
control in the field.
In the absence of power from the current transformers, the overcurrent control will
draw its power from the connected personal computer via the USB connection.
The overcurrent control features time-current characteristic (TCC) curves consisting
of phase-overcurrent curves and ground-overcurrent curves. The families of curves are
as follows:
• IEEE (ANSI. U.S.) curves per IEEE Standard C37.112-1996 and IEC curves per IEC
60255-3: U1, U2, U3, U4, U5, C1, C2, C3, C4, and C5.
• S&C standard speed curves (for use in place of conventional “E”-rated power fuses)
• S&C “K”-speed curves (for use in place of conventional “K”-rated power fuses)
• S&C “T”-speed curves (for use in place of conventional “T”-rated power fuses)
• Tap fault interrupter curves
• Main fault interrupter curves
The TCC curves can be customized into hundreds of different curves using a variety of
definite-time delay settings. For even more specialized shapes, there are two definite-time
settings that can be programmed. The definite-time settings can be programmed with
a minimum time value of 0 seconds, which is used to create an instantaneous overcur-
rent response. Ground Protection, Negative Sequence, and Sensitive Earth Fault
protection elements are also available. The factory default settings for the overcurrent
control are shown in the “Factory Default Protective Settings” section on page 35.
A choice of 50- or 60-Hertz operation is also offered.

Understanding the Status Display
The FAULT INTERRUPTER 1 and FAULT INTERRUPTER 2 orange LED displays will
indicate whether a fault interrupter has experienced a Trip event initiated by the
overcurrent control. If more than one fault interrupter has responded to a fault, both
LED displays will light. See Figure 14 on page 19.
During a Trip event, the FAULT INTERRUPTER LED will blink after passing the mini-
mum pickup level. If the current goes below the fault level and the control resets without
initiating a trip operation, the FAULT INTERRUPTER LED will turn white again. If the
fault interrupter trips, the LED will glow solid orange. The appropriate events (pickup,
timing, trip, or reset) are logged in the event log.
The CONTROL ENABLED indicator LED will flash green when the overcurrent control
is powered. When the control is operating normally, the indicator will blink. If the control
is in an error state, or a firmware update is being performed, the CONTROL ENABLED
indicator LED will glow a solid green. If the control is displaying solid green when the
firmware is NOT being updated, contact your local S&C Sales Office or the S&C Global
Support and Monitoring Center at 1-888-762-1100 (or 1-773-338-1000 outside the U.S.)
for support.
The OVERCURRENT CONDITION “A, B, and C” indicator LEDs show the phase involved
with a Phase Overcurrent Trip event, if one has occurred. If more than one phase is
involved in a Trip event, then more than one lamp may be lit. The Q and G indicators
will show whether there was a control-initiated Trip event in response to a Negative-
Sequence “Q” or Ground “G” protective setting. If more than one fault interrupter has
responded to a fault, then more than one lamp will be lit. See Table 3 for a key to the
overcurrent conditions:
Table 3. Overcurrent Conditions
