CHINT NJB1-X1 Relay phase sequence and phase failure protection device
CHINT NJB1-X1 Relay phase sequence and phase failure protection device,
NJB1-X1 relay (phase sequence, phase failure protection) is use 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.
