Claims

[Scope of utility model registration request]

A multi-pole circuit breaker provided with a detection element that detects abnormal current and at least one pair of main contacts that open in response to the detection element and whose openings are interlocked with each other;
A terminal block for connecting a load device connected to the output terminal of this circuit breaker is housed in a box, and a single-phase three-wire power line is introduced into the box, and one side voltage line of this power line is used to interrupt the circuit. a voltage switching device of a distribution board, which connects to one of the input terminals of the circuit breaker, and selects the neutral line and the other side voltage line of the power supply line by a connector and connects it to the other input terminal of the circuit breaker; In the
The first connector is equipped with an input terminal piece connected to the other side of the input terminal of the circuit breaker and a neutral side terminal piece connected to the neutral line at a predetermined interval in the insertion port. , an input terminal piece connected to the other side of the input terminal of the circuit breaker, and a voltage side terminal piece connected to the other side voltage line are installed in the insertion port at the predetermined interval. a second plug-in terminal portion, and a connecting tool surrounded by an insulator that allows both terminal pieces to be inserted into the first and second plug-in terminal portions to enable a short-circuit connection; The second plug-in terminal is connected in the vicinity of the plug-in port so that the connector inserted into one plug-in terminal can prevent the connector from being inserted into the other plug-in terminal. A voltage switching device for a distribution board, characterized in that the voltage switching device is arranged so as to be orthogonal to each other.
