Claims

[Scope of Claim for Utility Model Registration] 1. A side plate formed of a metal plate that supports an opening/closing mechanism that controls the contact and separation of a movable contact with a fixed contact, and an arc extinguishing device extending from the side plate to the arc extinguishing chamber side. It is characterized by comprising a commutator plate that also serves as a part of the grid, and a connection means that is provided between the side plate and a connection piece that is extended to the load side terminal and bypasses the overcurrent response element. Commutation device for hardwired circuit breakers. 2. The commutation device according to claim 1 of the utility model registration claim, characterized in that the connecting means, the end of the connecting piece, and the fixed side connecting end of the overcurrent responsive element are overlapped and fixed to the side plate. Commutation device for hardwired circuit breakers. 3. In the commutation device according to claim 1 of the utility model registration claim, the connecting means is connected by overlapping the end of the connecting piece and the fixed side connecting end of the overcurrent response element, and also by connecting the connecting means with a screw provided in the connecting part. A commutation device for a molded circuit breaker, characterized in that the tip of an adjustment screw that is screwed into a hole so as to be movable back and forth comes into contact with a side plate. 4. In the commutation device according to claim 1 of the utility model registration claim, the connecting means is connected to the end of the connecting piece by overlapping the fixed side connecting end of the overcurrent responsive element, and
A commutation device for a molded circuit breaker, characterized in that an extension end bent at a right angle is brought into sliding contact with a side plate.
