Phase Failure Voltage Monitor Three-Phase — MGD1DR

Description

A phase failure relay may have one or more relay outputs, all of which are typically set up in a failsafe manner. When the supply circumstances fall within the permitted tolerances, these relays will activate and close the circuit.

Specifications:

Contact Capacity: AC250V 5A

Rated Operation Voltage: Three Phase AC 415V

Over Voltage Protection: AC415V-495V

Under Voltage Protection: AC335V-415V

Operation Time of Over Voltage: 2s-8s adjustable

Operation Time of Under Voltage: 2s - 8s adjustable

Open Phase Protection: a<2s

Phase Sequence Protection: If any phase line is exchanged at will after the phase sequence is identified, the motor won't start, the fault indicating lamp will turn on and the protector will operate reliably
