First-class power distribution box: The power distribution cabinet for construction is used for the construction of the construction site. It is specially designed for the special situation of the construction site. It is in line with the relevant construction electricity specifications and standards of the construction department. The complete set of products can form a complete three-level protection system for construction electricity, achieve the purpose of one machine, one gate and one protection, and is very suitable for various projects that meet the standards.
The first-level cabinet adopts bottom-in and bottom-out cables, and the front door is opened. The main busbar is connected by copper bars, with good contact. It has a metering system inside, which is safe and beautiful. The top of the rainproof box is suitable for field work.
