PROBLEM TO BE SOLVED: To provide a switch gear that makes it possible to perform the laying work of cables and the like with no need of the mounting work of a current transformer or a zero-phase current transformer inside a narrow conductors room, and whose workability at the time of its assembly is improved. SOLUTION: Three pieces of conductors that constitute contact terminals 21 for three phases are molded integrally with an insulating material 23. The current transformers 24 are each mounted to at least two pieces of these three conductors, and zero-phase current transformers 25 are mounted outside the converging portion of the three conductors converging via prescribed insulation distances with the insulating material 23. These current transformers 24 and zero-phase current transformers 25 are molded integrally in the insulating material 23. COPYRIGHT: (C)2005,JPO&NCIPI |
