Claims

[Scope of utility model registration request]

Structure of an insulating barrier including a rectangular insulating plate inserted between at least phases of a three-phase switch whose current-carrying part is supported via an insulating support member from a support base having a supporting surface in the vertical direction and housed in a switchboard. And,
The rectangular insulating plates are rigidly connected to each other between their respective edges to form a frame, and at least one of the insulating plates has a tip near the edge facing the support surface of the support base. 1. A structure of an insulating barrier for a switch, characterized in that a holding metal fitting having a hook portion formed thereon is fixed to the support base so that three phases can be integrally attached to the support base.
