This is a Voltage Sensing SPP senses the presence of the three phases and their sequence.If any one of the phases is absent or the sequence of the three phases is reversed it operates the relay.This is perfectly suitable for the protection of the three phase motor. It Automatically resets when the fault condition is gone. Auxiliary Supply : 440 V AC between R & Y Input from 3 Phase of R, Y, B LED indicator for power &trip Unbalance voltage for tripping = 50 to 60 V Output relay contact rating : 5A at 230V AC Auto reset when 3 phase supply is restored Voltage Sensing operation Field proven design Enclosure : Din Rail Mounting Size : 60 X 70 X 110 mm
