Product Advantages

Highlight

Diverse Functional Units

Drawer units of the same type feature excellent interchangeability. The functional unit doors are equipped with mechanical interlocks connected to the operating mechanisms of the main circuit switches, ensuring maximum operational safety.

Highlight

Reliable Busbar System

The system adopts a three-phase five-wire system. The horizontal busbars are installed at the top of the cabinet, while the N line can be installed either at the top or at the bottom of the cabinet, and the PE line is installed at the bottom. Copper busbars are utilized, offering high mechanical strength and excellent heat dissipation.

Highlight

High Safety & Protection

Equipped with a mechanical interlock, the door can only be opened when the handle is in the "OFF" position, effectively preventing accidental operation. Additionally, functional unit compartments are isolated by metal plates to prevent fault propagation.

Highlight

Rational Structural Design

The basic frame features a modular assembled structure, securely connected with screws to eliminate welding deformation and residual stress, significantly improving installation precision. With modular mounting holes throughout the frame and components, assembly is exceptionally flexible and easy. Internal structural parts are galvanized, while external structures undergo phosphating before receiving an electrostatic epoxy powder coating, ensuring excellent corrosion resistance and a sleek appearance.
