<p>PURPOSE: A molded case circuit breaker is provided to implement a sealed structure with vertically coupling a bottom base and a top base, thereby improving the assembling property of a product. CONSTITUTION: A molded case circuit breaker includes multiple fixing members(110), multiple moving members, multiple arc chambers, a bottom base(140), and a top base(150). The fixing members form fixing contact points. The moving members form moving contact points. The arc chambers remove arcs from the contact points. The bottom base separately houses the arc chambers. The top base separately seals the arc chambers.</p> |
