Tronic Phase Failure And Sequence Relay 415V

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 Warranty: 1 Year
