Monitoring relays provide reliable protection and diagnostics by tracking key electrical parameters such as voltage and current. Designed for AC or DC applications, they detect under/overvoltage conditions, current thresholds, and potential faults in motors, heating systems, lighting, and other equipment. These devices help prevent equipment damage and ensure operational stability across industrial and commercial installations....
