Type of switch for three-level distribution box

Type of switch for three-level distribution box

Fusible switchboards are designed for commercial, industrial, and service entrance applications to protect and switch feeder and branch circuits. Each panelboard unit includes a switching contact structure with an instantaneous trip element. The complete set of products can form a complete three-level protection system for construction electricity, achieving the goal of one machine, one switch, and one protection, which is very suitable for various standard engineering applications. According to the hierarchical. The three-level distribution system refers to a system that distributes electric power through three levels of distribution devices from the incoming power line at the construction ...
