It provides all-round protection against overload, short circuit, under-voltage, phase reversal and motor stall. It also offers specialized overtorque protection that triggers alerts or protective actions when motor torque exceeds a user-set threshold to protect the driven load. Its ground fault protection function eliminates DC components from dangerous currents to shield motors from phase-to-ground faults.
It can real-time monitor key motor parameters including current, voltage, energy consumption, temperature and torque. It supports up to twelve programmable resistance temperature detector inputs that send alerts for dangerous ambient temperature changes. It has a built-in simulation function that can simulate input values, fault conditions and pre-trip conditions to test the relay’s operational effectiveness without disrupting actual motor operation.
The enhanced faceplate with an LCD screen clearly displays motor operating status and fault information. The fully drawout case design allows hot-swapping, which simplifies maintenance processes and reduces equipment downtime during repairs or replacements.
With RS232 and RS485 communication ports, it can seamlessly connect with various industrial control systems and upper monitoring platforms. It realizes centralized management of multiple motors and enables remote parameter configuration and data retrieval, improving the intelligence level of industrial motor control systems.
It is widely used to protect motors in key equipment such as extruders, conveyors, cranes and fans in machinery manufacturing plants and automobile production lines. It ensures continuous operation of production lines by preventing motor faults from causing production disruptions.
It is applied to motors in drilling rigs, pipeline compressors and oil well pumps. Its robust structure and resistance to harsh conditions adapt to offshore and onshore oil and gas extraction environments, avoiding safety accidents and economic losses caused by motor failures during oil and gas extraction and transportation.
It is installed in motors of auxiliary equipment such as cooling fans and water pumps in substations and power distribution automation systems. It also protects motors in public utility facilities, ensuring stable operation of power supply systems and reliable operation of public infrastructure.
It safeguards motors in mixers, reactors and conveying pumps in chemical plants, as well as motors in crushers and blast furnace fans in metallurgical plants. Its corrosion-resistant and high-temperature-resistant performance copes with corrosive gases and large temperature fluctuations in these industrial environments.
It is used to protect large motors in heating, ventilation and air conditioning systems, elevators and water supply pumps in high-rise buildings, shopping malls and large office complexes. It guarantees the stable operation of building supporting facilities and maintains a comfortable and safe environment for building users.
