Crompton Instruments - 253-PVEW-RRBX-C5-EC VOLTAGE PROTECTOR, 3PHASE, 4 WIRE, 240V, 50HZ, 2 RELAYS AND 2 SET POINT

3 Phase Trip Relay, Over and Under Current

The 253 Series AC voltage protector provides continuous surveillance of a monitored electrical 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.

Dependable, this DIN and Wall mountable Protection Relay can be used for under and over-voltage detection, starting standby generators, operation of mains failure units and switching standby supplies. An illuminated LED indicates when the relay is energised and this three-phase, four-wire model protects each phase independently.
