Metering Devices, Protective Relays, Software and Connectivity
Protective Relays
Options and Accessories
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 indicator is rated
110/120 Vac 50/60 Hz for a
maximum indicator load of
0.5 amperes.
Indicating Ammeter
The optional indicating
ammeter connects to the
sensor terminals through
a momentary contact
pushbutton, and will indicate
(in amperes) any ground fault
current flowing through the
sensor. Kit includes the
ammeter and pushbutton.
Not UL listed.
Shunt Trip Attachments
Use 120 Vac shunt trips.
Face Plate
Recommended when
these relays are semi-flush
mounted, to close the door
cutout opening.
Options
Additional optional equipment
can be added to the protection
system to meet the
requirements of the specifying
engineer, including:
●
Ground fault test panel
●
Ground fault warning
indicator relay
●
Ground fault indicating
ammeter
GFR relays are available with
zone selective interlocking
circuitry to interlock 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 molded case circuit
breakers, or may be ordered
factory installed in the breaker.
