The XJ3-G Phase Failure Relay is designed for monitoring three-phase AC 380V electrical systems and providing protection against phase disconnection and phase errors. With 1NO + 1NC output contacts, long mechanical life and flexible mounting options, it is suitable for industrial control panels, motor control systems and three-phase electrical equipment.
The XJ3-G Phase Failure Relay provides continuous phase-condition monitoring for three-phase AC 380V power systems. It is designed to detect abnormal phase conditions such as phase disconnection and phase error, helping control systems respond before electrical equipment continues operating under unsuitable supply conditions. The relay provides 1 normally open and 1 normally closed contact, allowing convenient integration with contactors, motor starters and other control components. With a mechanical life of up to 1 × 10⁶ operations, an operating temperature range of −5°C to +40°C, and support for both device-type and guide-rail installation, the XJ3-G is suitable for industrial electrical control and equipment protection applications.
