Claims

[Scope of utility model registration request]

In a drawer type breaker comprising a shutter that protects fixed terminals arranged on the drawer frame when the breaker main body is pulled out from the drawer frame, a U-shape provided on the inside of both sides of the drawer frame. Two shutters that slide vertically symmetrically using a groove as a guide, one end of which is attached to both ends of each of the two shutters so that the two shutters can slide along the U-shaped groove, and the other end of the shutter. The receiver, which is pressed by the breaker main body, includes two sets of two links supported so as to open in a fan shape with the plate as a fulcrum, and one end of which is fixed to the inner side of the side of the drawer frame. A guide rod whose other end passes through the vicinity of the two shutters and whose other end passes through the plate and slides it, and a guide rod which prevents the two shutters from opening vertically symmetrically around the guide rod. A protective structure for a drawer-type breaker, characterized in that it is provided with a tension spring provided with a tension spring.
