Product Overview

The modular AC metal enclosed switchgear is a safe and reliable power distribution equipment suitable for indoor installation. It mainly uses high-quality cold-rolled sheet metal as the enclosure, processed through cutting, bending, welding, and other processes, with a reasonable structure and beautiful appearance. The equipment is primarily composed of high-voltage load switch, load switch-fuse combination appliance, and other electrical components. The busbar system adopts premium raw copper busbars, with reliable insulation treatment and excellent conductivity. The main switch and fuse are equipped with reliable anti-misoperation mechanical interlock devices to ensure personal safety.

The equipment can be used in various power systems such as industrial and mining enterprises, residential communities, schools, parks, etc. It can be configured with a single or dual power supply, and the electrical schematic can be designed according to user requirements. It meets the requirements of IEC60298 and GB3906 standards.

The equipment has an open structure, good ventilation conditions, high reliability, and is easy to install and maintain.
