Disclosed is a trip device of a circuit breaker, the device including: a rectifying unit (200) converting an AC (Alternating Current) voltage applied to the circuit breaker to a DC (Direct Current) voltage; a smoothing unit (210) connected to the rectifying unit in parallel to mitigate ripples of the converted DC voltage; and a trip coil (220) connected to the smoothing unit (210) in parallel to determine whether to trip the circuit breaker. |
