Construction site three-level switch distribution box
Connects to end-use equipment via switch boxes, forming a three-tier power distribution system. Residual current devices (RCDs) at both the tertiary (equipment-level) and secondary (zone-level) stages. Ensures safe disconnection in case of faults or leakage currents. 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. After stepping down the voltage through the transformer's low-voltage side (0. 4kV), power is distributed to a main distribution panel (primary distribution box). From there, it is routed to individual building distribution boxes (secondary distribution boxes), which subsequently supply power to unit-level distribution boxes. 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 site to the electrical equipment.
