Ground
Fault Protection Relays System GFR-2
CSA
approved GFR-2 relay is housed in a standard track mount DIN enclosure.
Our
Ground Fault System protects industrial electrical equipment such
as motors, transformers and feeders against damage caused by low
magnitude ground currents. GFR-2 operates reliably on either high
or low resistance grounded distribution systems.

GFR-2
can operate with any Sensor supplied by Skymatic Controls or others.
Ordering Information provides more details about the various Relay
options, tripping ranges and selection of Sensors.
Ground
Fault Protection Relay GFR-2 works with a Zero Sequence Current
Transformer (Sensor). When the Ground Fault occurs, the Sensor sends
the signal to trip GFR-2 relay. DPDT output contacts are available
to operate breakers, annunicators or other devices.
