Zusammenfassung:PROBLEM TO BE SOLVED: To provide a voltage display device for a breaker capable of preventing a voltage display member from being significantly influenced by heat generation of a live part, allowing reduction of the number of components, easy to mount and capable of preventing a plug from being tilted by the voltage display member. SOLUTION: This voltage display device for a breaker is so structured that a voltage changeover is carried out by rotating the plug 11 on the power source side; and the voltage display member 16 installed in the vicinity of the upper surface of a case is allowed to be rocked by directly engaging it with an insulating plug fixing member 12 for retaining the plug 11. Since there is no energizing spring like a conventional one, the voltage display device is easy to mount, and the plug is never tilted by the voltage display member. COPYRIGHT: (C)2004,JPO
