ELASTIC PRESSING UNIT AND MOLDED CASE CIRCUIT BREAKER HAVING THE SAME

摘要

PURPOSE: An elasticity pressing unit and a MCCB(Molded Case Circuit Breaker) thereof are provided to secure the operating reliability and stability by preventing the deformation of a part. CONSTITUTION: A MCCB comprises a plurality of fixed contact points and a plurality of movable contact points. A rotating pin(150) is connected to a plurality of movable contact points. A device part(140) is connected to the rotating pin. The device part simultaneously rotates a plurality of movable contact points. An elasticity pressing unit(160) applies elastic force to the rotating pin in order to move the rotating pin to an inserting position. The elasticity pressing unit comprises a pusher and a spring. The pusher pressurizes the rotating pin. The spring applies elastic force to the pusher in order to contact the pusher to the rotating pin.
