Japanese Patent JP2018101553
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an earth leakage circuit breaker facilitating assembly work by unitizing a link mechanism as one piece with a relatively simple configuration.SOLUTION: An operation handle 2 switches between a closed state and an open state of an earth leakage circuit breaker 10. A movable element 4 moves a movable contact across a position in contact with a fixed contact, and a position not in contact with the fixed contact. A link shaft 5 is connected with the operation handle 2 and the movable element 4, and associates a position of the operation handle 2 with a position of the movable element 4. A frame 1 has sidewalls 1a, 1b erected from a bottom face 1c in a state of facing each other. The operation handle 2, the movable element 4 and the link shaft 5 are assembled with respect to the sidewall 1a. The sidewall 1b is provided so as to be able to change an erection angle with respect to the bottom face 1c, and prevents the operation handle 2, the movable element 4 and the link shaft 5, assembled for the sidewall 1a, from coming off.SELECTED DRAWING: Figure 3
