Voltage Monitor and Control

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
