Title:
TERMINAL STRUCTURE OF CIRCUIT BREAKER
Document Type and Number:
Japanese Patent JP2015222736
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a terminal structure of a circuit breaker having a selection type terminal device, in which a connection state of bus bars to a plurality of circuit breakers and voltages supplied from the bus bars to the circuit breakers can be easily checked from the front face side of the circuit breakers, furthermore, a voltage cannot be changed in a state where leg portions of the bus bars and connection portions are connected to terminal portions of the circuit breakers, and an operator rarely misidentifies a connection bus bar or a supply voltage so that an electrical failure rarely occurs.SOLUTION: A terminal structure of a circuit breaker includes: a movable power supply side terminal that is one of power supply side terminals, in which a connection position to bus bars is variable, and that is connected to a predetermined bus bar selected from the bus bars of respective phases in a distribution board; a voltage display portion that previously displays a plurality of power supply voltages that can be applied in the distribution board; and a concealing plate that conceals a display of a power supply voltage that is not actually applied, with a movement of the connection position of the movable power supply side terminal. Thus a display of a voltage actually applied is exposed to be visible from the outside.
