AC Voltage with Adjustable Differential | Crompton Protector Trip Relays

Hotline : 0976 33 55 58

AC voltage protectors provide continuous surveillance of the monitored circuit. When the measured voltage moves outside the set point limit for longer than the time delay, the relay will operate giving an alarm or initiation signal. The protector can be used for under and over-voltage detection, start standby generators, operation of mains failure units and switching standby supplies. An illuminated LED indicates when the relay is energized. The three-phase, three or four-wire models, protect each phase independently.
