Abstract
The present disclosure relates to a 3-phase undervoltage trip device capable of automatically tripping a circuit breaker based on an under-voltage of a 3-phase line voltage, including lines to which a 3-phase power is applied. The undervoltage trip device is connected to lines to which a 3-phase power is applied and configured to operate to automatically trip a circuit breaker when an open phase condition occurs on any one of three phases of the power. As the undervoltage trip device automatically trips the circuit breaker when the open phase condition occurs on any one of three phase, occurrence of the open phase condition due to disconnection or an accident on the line may be easily detected.
