CHINT NJB1-X,X1 Phase Sequence Phase failure Protection Relay Over-/Under-voltage for AC Motor, fan 3-Phase 380-400V
NJB1-X,X1 series phase failure and phase sequence protection relay is used to provide overvoltage, undervoltage and phase failure protection in three-phase AC circuits and phase sequence protection in irreversible transmission devices and features reliable performance, wide application and convenient use.
The protector starts to function when it is connected to the power control circuit in accordance with the drawing. When the fuse of any phase of the three-phase circuit is open or when there is a phase failure in the power supply circuit, the NJB1-X,X1 operates immediately to control the contact to cut off the power supply of the AC contactor coil of the main circuit so that the main contact of the AC contactor operates to provide the load with phase failure protection.
When the phases of a three-phase irreversible device with predetermined phase sequence are connected incorrectly due to maintenance or change of the power supply circuit, the NJB1-X,X1 series will identify the phase sequence, stop supplying power to the power supply circuit and achieve the goal of protecting the device.
