PURPOSE: A trip device of a circuit breaker is provided to prevent damage to a load and a line by functioning as a UVT(UnderVoltage trip device) and a remote trip device. CONSTITUTION: A rectifying unit(200) and a smoothing unit(210) convert an AC voltage applied to a circuit breaker into a DC voltage. A trip coil(220) is connected in parallel to the smoothing unit. A switching device(230) is connected in parallel to the trip coil and is on and off according to an external control signal. The rectifying unit comprises a bridge diode circuit. |
