Claims

[Claims for Utility Model Registration] (1) In a circuit disconnector having an operating handle that can be switched between an ON position and an OFF position and a trip button that can be tripped from the outside, the operating handle is switched between the ON position and the OFF position. An operating handle locking device for holding the operating handle in position, the operating handle having a first opening through which the operating handle passes when the operating handle is in the ON position, a second opening through which the operating handle passes when the operating handle is in the OFF position, and a first opening and a second opening that the operating handle passes through when the operating handle is in the ON position. a blocking part that is between the two openings and prevents the operating handle from moving from one of the openings to the other; and an operation in which the operating handle is passed through the first opening or the second opening. a locking plate having a cover portion that covers the trip button when the handle is in the locked position; and a locking plate that is secured to the circuit board or disconnector and that moves the locking plate relative to the support plate when the operating handle is in the locked position and in the first opening. or a support plate movably supporting the second opening between an operation handle unlocked position in which the second opening is detached from the operation handle, and a locking means for holding the lock plate in the operation handle lock position with respect to the support plate. An operating handle locking device for circuit breakers and disconnectors. (2) The lock plate has a cover portion that covers the clamping member that fixes the support plate to the circuit or disconnector when the lock plate is in the lock position of the handle. Device.
