摘要： Disclosed is a circuit breaker. The circuit breaker includes an arc exhaust port for exhausting an arc generated in the inner box; an outer box receiving the inner box and including an arc passage for exhausting the arc from the exhaust port to an outside; and an arc guide part for guiding the arc from the arc exhaust port into the arc passage, wherein the arc guide part includes: an upper guide; a lower guide spaced apart from the upper guide; and a connecting part connecting the upper and lower guides to each other in a longitudinal direction.

摘要： A molded case circuit breaker (MCCB) includes a case, an interrupter assembly, an exhaust guide part, an exhaust cover, a sealing groove and a sealing projection. The interrupter assembly is mounted inside the case, and has an arc gas exhaust port to exhaust an arc gas generated inside the case. The exhaust guide part is disposed between the interrupter assembly and the terminal part, and has an exhaust chamber therein to provide an arc gas passage between the arc gas exhaust port and a vent chute of the terminal part. The exhaust cover is mounted to the case in a structure covering the exhaust guide part, to seal the arc gas passage. The sealing groove is formed in an inner surface of the exhaust cover. The sealing projection is formed on the arc gas exhaust port of the interrupter assembly, to be inserted and coupled into the sealing groove.

摘要： Disclosed is a molded case circuit breaker. The molded case circuit breaker includes include: a case; an interrupter assembly installed in the case, and provided with an arc gas outlet; an exhaustion guiding portion disposed between the interrupter assembly and the terminal portion; an exhaustion cover mounted to the case, with a structure to cover the exhaustion guiding portion; and exhaustion guides spaced from each other in the exhaustion guiding portion, in a direction perpendicular to an arc gas discharge direction, in a state where the gas divergence portion is disposed therebetween, the exhaustion guides forming the arc gas passage together with the gas divergence portion. Under such configuration, arc gas discharged out of the arc gas outlet can be rapidly discharged to outside through the exhaustion guides, without an eddy current.
