GFR relays are available with zone
selective interlocking circuitry to inter-
lock several relays within the same
system. This allows the relay which
detects a ground fault to instantly clear
the fault by tripping the disconnect
device. The relay simultaneously sends
a signal to relay units “upstream” from
the fault to time delay or to block their
operation completely. Current sensors
in various designs provide a range
of “window” sizes to accommodate
standard bus and cable arrangements.
Shunt trip attachments may be ordered
for field mounting in Eaton’s Cutler-
Hammer molded case circuit breakers,
or may be ordered factory installed in
the breaker.

Test Panel (120 Vac)
Used to test the ground fault system,
to give an indication the relay has
tripped the breaker, and to reset the
relay after tripping. These functions
may be separately mounted pilot
devices.
Note: When a mechanically reset relay is
used with a test panel, both the relay and
test panel must be reset following either a
simulated ground fault test or actual ground
fault. Not UL listed.

Ground Fault Warning Indicator
This is an accessory item for use with
GFR relays with interlocking circuitry.
At approximately 30 – 50% of the relay
pickup setting, the indicator switches
separate 120 Vac control power to a
lamp or relay, (not included) to give an
indication of a ground fault. The indi-
cator is rated 110/120 Vac 50/60 Hz
for a maximum indicator load of
.5 amperes.

Indicating Ammeter
The optional indicating ammeter
connects to the sensor terminals
through a momentary contact push-
button, and will indicate (in amperes)
any ground fault current flowing
through the sensor. Kit includes the
ammeter and pushbutton.
Note: Not UL listed.
