NJB1-X1

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 2. Type designation N JB 1 - X1 Function code: X1: phase sequence, phase failure relay Design sequence No. Protection and monitoring relay Company code Relay Protection Relay 3. Operation conditions 3.1 Rated operational voltage: AC 200V~500V 3.2 Operation time: phase sequence, phase failure ≤ 0.1s 3.3 Contact capacity: Ue/Ie: AC-15 220V/0.75A, 380V/0.47A; Ith: 3A 3.4 Mounting type: rail type, installation type 3.5 Power consumption: ≤3VA 3.6 Note: In normal operation, the N/O contact of the relay is closed, the operation indicator is on. 4.
