Product Advantages
Excellent Electrical Performance
Excellent dynamic and thermal stability, capable of withstanding short-circuit current impacts. The main circuit plug adopts a laminated structure, and the spring is made of manganese steel for strong overload current capacity. The secondary connector has a long contact travel, and wiring and outgoing lines do not interfere with each other, facilitating cable routing.

High Versatility
Components are fastened together to meet various structural forms, IP ratings, and environmental requirements, while avoiding welding deformation.

Easy Maintenance
Drawers can be plugged and unplugged under voltage, eliminating the need for full cabinet power outage during maintenance, achieving zero business interruption. Maintenance personnel operate without risk of electric shock, significantly improving operational efficiency.

Reasonable structural design
The internal installation is flexible and convenient, with two structural options available: fully assembled and partially welded. The horizontal main busbars are arranged flat at the rear of the cabinet, enhancing the busbars' resistance to electrodynamic forces and ensuring high short-circuit strength for the main circuit.
