XJ3-G1 Series Phase-Failure And Phase-Sequence Protection Relay Over/Under-Voltage 3 Phase Protector
XJ3-G1 Series Phase-Failure And Phase-Sequence Protection Relay Over/Under-Voltage 3 Phase Protector
Product Description:
The XJ3 series phase failure and phase sequence protection relay is designed for over-voltage, under-voltage, and phase failure protection in three-phase AC circuits, as well as phase sequence protection in irreversible drive systems. It features reliable performance, wide application range, ease of use and so on.
When the protection device is connected into the power control circuit, it can perform the protection function. In a three-phase circuit, if any one phase fuse opens or there is a phase failure in the power supply line, the XJ3 relay will immediately activate, and the control contacts will cut off the main circuit AC contactor coil power, thereby causing the AC contactor main contacts to actuate and protect the load from phase failure.
For three-phase irreversible equipment, if it is incorrectly connected with the original phase sequence due to the maintenance or change of power supply line after phase sequence identification, the XJ3 series can detect the incorrect phase sequence and work reliably, stop supplying power to the circuit, achieving the purpose of protecting the equipment.
Product Feature:
■ Small size, light weight and compact structure.
■ High delay precision and reliable.
■ Long performance.
■ This product is mainly composed of shell, main control circuit and wiring base.
■ Equipped with running, phase fault indicator.
