G59 Loss of Mains Protection Relay - Three Phase - 4 Wire

The fully self-contained KCG598E provides precision protection against malfunction and human and operational hazards under loss of mains conditions.
The DIN rail mounted digitally controlled unit meets the protection requirements for generators connected to mains supply, such as defined in the G59/2 and similar recommendations.
Less wiring, no extra modules. Operating mode is selected by simple auxiliary contacts on the generator breaker and on the mains breaker. LEDs and open collector outputs indicate operating mode and ìFirst Upî cause of trip.
State-of-the-art digital technology throughout, with quartz-controlled Loss of Mains detection. True RMS
Self powered from monitored voltage input:
