GAE Phase Failure Relay (PFR) GC1100 Nominal voltage : 380Vac Frequency : 50 Hz Set point range : adjustable 5% … 25% of Nominal voltage Relay type : SPDT – Contact rating 5A (cos? = 1), 250 Vac Burden : 5VA / 4W (max) Operating temperature : 0° C … +50° C Storage temperature : -10° C … +70° C Relative humidity : 95% (non condensing) Mounting : DIN rail 35 x 7.5 mm
GC1100 phase failure relays protect three phase lines, transformers, motors, generators, and another three phase loads against phase unbalance, phase loss, and phase reversal.
The output relay energizes and the green BALANCE LED lights when a balanced input with the proper phase sequence is sensed. The output relay de-energizes and the BALANCE LED goes out when a fault condition is detected.
