在に設けた事を特徴とする回路しゃ断器。A circuit breaker with contacts and a switching mechanism housed in an insulating cover and an insulating case is installed on multiple interphase insulation barriers that partition the terminals provided at the end of the circuit breaker, and the terminal part is covered with a terminal cover. A recessed latching groove is provided in the upper part of the outer wall of the cover, and a cut groove is provided at the tip of the cover into which the plurality of tips of the terminal cover are fitted, and a protruding piece is provided at the tip of the top surface.
Insert a terminal cover with a convex part on the inside of the tip of the side surface of the terminal cover, which has a partition plate that surrounds both sides and the rear surface and whose end reaches the barrier, into the cut groove of the tip of the barrier at the tip of the insulating cover. The device is characterized by inserting a partition plate, fitting and locking the convex portion of the terminal cover into the locking grooves provided on the outside wall of the barrier at both ends of the insulating cover, and attaching the terminal cover in a tight manner so that it can be attached and detached freely. circuit breaker.
