Abstract

PROBLEM TO BE SOLVED: To prevent an erroneous operation of a circuit breaker while restricting an increase of a space occupied by a circuit breaker in a casing.SOLUTION: Comparing the preferred embodiment of the present invention with the prior art shown in Fig.5 in reference to a space of a circuit breaker 5 occupies in a casing 1 (a volume of a storing cavity 10) shows that the space can be reduced in the preferred embodiment by an amount in which the circuit breaker 5 is inclined to cause the lower part of a case 50 to move more forward than its upper part. That is, the preferred embodiment has a holding member 6 for holding the case 50 of the circuit breaker 5 while being inclined in such a way that an angle θ formed by a normal line direction, so that it is possible to prevent an erroneous operation of the circuit breaker 5 while restricting an increase of space occupied by the circuit breaker 5 within the casing 1.
【課題】筐体内における回路遮断器の占めるスペースの増加を抑えつつ回路遮断器の誤操作の防止を図る。 【解決手段】本実施形態と図5に示した従来例とで筐体1内における回路遮断器5の占めるスペース(収納凹所10の容積)を比較すると、回路遮断器5が傾いてケース50の下部が上部よりも前方へ移動している分だけ、本実施形態の方が前記スペースを小さくできる。つまり、本実施形態は、筐体1の前面とケース50の前面のそれぞれの法線方向のなす角度θが鋭角となるように回路遮断器5のケース50を傾けて保持する保持部材6を有しているので、筐体1内における回路遮断器5の占めるスペースの増加を抑えつつ回路遮断器5の誤操作の防止を図ることができる。 【選択図】 図1
