Description

technical field

[0001] The present invention relates to a relay terminal device which is suitable for a wiring circuit breaker equipped in a distribution board, a power distribution board, etc., and which is externally installed on a power supply side terminal of the circuit breaker to connect electric wires from a power distribution system. Background technique

[0002] As relay terminal devices used for connecting electric wires (such as rubber insulated flexible cables) of the power distribution system to the above-mentioned circuit breakers, there are known relay terminal devices corresponding to U, V, and W phases of the main circuit. a box-shaped terminal connector; and a terminal block (attachment to a circuit breaker) for wire connection in which a terminal board connected between the terminal connector and a main circuit terminal of a circuit breaker is installed in an insulating frame (resin case) (For example, refer to Patent Document 1).
