Product Description
GFR Relay
Product Description
Eaton’s Cutler-Hammer GFR ground
fault relays, current sensors, test
panels and accessory devices are UL
listed by Underwriters Laboratories
in accordance with their standard for
Ground Fault Sensing and Relaying
Equipment, UL 1053, under File
E48381.
Note: Suitable for either surface or semi-
flush mounting.
A Type GFR ground fault protection
system, when properly installed on a
grounded electrical system, will sense
phase-to-ground fault currents. When
the level of fault current is in excess
of the pre-selected current pickup and
time delay settings, the GFR relay will
initiate a trip action of a disconnect
device, which will open the faulted
circuit and clear the fault.
The GFR devices are UL Class I devices
designed to protect electrical equip-
ment against extensive damage from
arcing ground faults.
A basic Type GFR ground fault protec-
tion system consists of a ground fault
relay, a ground fault current sensor
and a disconnect device equipped with
a shunt trip device. This disconnect
device can be a molded case circuit
breaker, a power circuit breaker, a
bolted pressure switch or other fusible
disconnect device, suitable for applica-
tion with UL Class I Ground Fault
Sensing and Relaying equipment.
Note: Relays are also listed with CSA under
their file number 43357.
