NJB1-X1 Relay (Phase Sequence, Phase Failure Protection)
1. General
NJB1-X1 relay (phase sequence, phase failure protection) is used as an phase sequence and phase failure protection device in control circuits with an AC voltage of 200V~500V and a frequency of 50Hz to make and break the circuit. It cannot monitor the phase failure of motor load. The products meet the requirement of standard IEC 60947-5-1
