The CHINT NJBK Series Motor Protection Relay is an electronic device designed to protect electric motors from damage.  It does this by monitoring various electrical conditions, such as current, and can detect problems like overloads, phase loss, and unbalanced current. When a fault is detected, the relay acts to trip the circuit breaker, disconnecting the motor from the power supply and preventing damage.
