<P>PROBLEM TO BE SOLVED: To provide a switch unit for a distribution panel which can miniaturize the distribution panel and facilitate maintenance of various devices for constituting the distribution panel. <P>SOLUTION: A main circuit including power supply side junctions 17, a circuit breaker 18, current transformers 19, zero-phase-sequence current transformer 20, an electromagnetic contactor 21 and load side junctions 22 electrically interconnected through connecting conductors 25-29 is mounted in a supporting frame 8. The circuit breaker 18 and the electromagnetic contactor 21 are disposed in parallel. The current transformer 19 and the power supply side junctions 17 are disposed for the circuit breaker 18, and the zero-phase current transformer 20 and the load side junctions 22 are disposed for the electromagnetic contactor 21 in the depth direction orthogonal to the direction of the circuit breaker 18 and the electromagnetic contactor 21 disposed in parallel. <P>COPYRIGHT: (C)2003,JPO |
