Abstract (en)

This application includes a moveable element being rotatably installed on a main body, the moveable element forming a pressure unit with a constant gradient in one side thereof, a moveable contact being formed to correspond to the gradient of the pressure unit to be fixed by the pressure unit and a fixable element being in a contact with the moveable contact. This application provides a molded case circuit breaker. The molded case circuit breaker may prevent a moveable contact deviation according to a solder fusion between a moveable element and a moveable contact although a temperature of a current carrying unit excessively increases when a fault current flows in, may form a moveable contact of a gradient shape corresponding to a pressure unit shape to increase a current carrying reliability despite inflow of the fault current and may prepare a weld unit between a pressure unit and a moveable contact to have a pressurized contact structure capable of maintaining a fixed factor such as re-welding the pressure unit and the moveable contact despite melting and cooling.
