Disclosed is a trip device of a circuit breaker, the device including: a rectifying unit converting an AC (Alternating Current) voltage applied to the circuit breaker to a DC (Direct Current) voltage; a smoothing unit connected to the rectifying unit in parallel to mitigate ripples of the converted DC voltage; and a trip coil connected to the smoothing unit in parallel to determine whether to trip the circuit breaker. |
