The JR series protective relay is a key device for fault detection and control protection in power systems, widely used in low- and medium-voltage distribution systems. It provides a variety of protection functions, including overcurrent, undervoltage, phase failure, phase sequence, imbalance, and overload, effectively preventing damage to electrical equipment caused by abnormal operation or faults.
The JR series protective relay features fast response, high sensitivity, and reliable operation, making it suitable for monitoring and automatically protecting equipment such as distribution transformers, motors, and capacitors. Flexible installation allows for easy integration into various control systems, and it can be combined with circuit breakers and contactors to implement tripping or alarm functions, enhancing the safety and stability of power system operations.
