PROBLEM TO BE SOLVED: To provide a switchgear, which enables the automatic electrical interlock of the controller of a breaker, when the breaker is attached/detached to/from a main circuit. SOLUTION: One of a pair of female and male connectors 3a and 3b of the control circuit of a breaker 2 is fixed to the breaker 2, and the other is slidably placed in a guide groove formed in a guide plate 3c fixed to a sidewall in a box 1a. The guide groove is composed of a straight groove, which is in parallel with a direction in which the breaker 2 is taken into/from the box 1a and a partial inclined groove which is bent and inclined toward the breaker 2 side. When the breaker 2 is attached/detached to/from a main circuit, the pair of female and male connectors 3a and 3b of the control circuit are automatically fit-connected/disconnected to/from each other at a predetermined position of the taking in/out of the breaker 2. |
