PROBLEM TO BE SOLVED: To prevent the intrusion of a small animal into a bare charged section. SOLUTION: A drawer type circuit breaker 1 uses a circuit breaker main body 2, a member 62, and a frame body 3 which is integrally constituted with the member 62 and has a side plate section 31 having opened rectangular pipe- like shapes at both ends so that the main body 2 can be housed in the frame body 3 and an end plate section 32 which closes the entire area of one opened end of the section 31. A closing plate 21 which is constituted so that a gap G2 can be formed between the end face of the plate 21 facing the side plate section 31 and the side plate section 31 when the plate 21 is attached to the edge section 8a of the breaker main body 8 and another closing plates 22 and 22 which are constituted so that gaps G2 can be respectively formed between the end faces of the plates 22 facing the member 62 and the member 62 when the plates 22 are mounted between a guide member 83 and moving devices 82. The gaps G2 are set at about 10mm which is smaller than the size of a small-animal, such as a rat, a snake, etc. |
