Product Features

The frame uses aluminum-zinc coated double-folding edge technology.

The top cover of the horizontal busbar area is detachable.

Features three types of functional unit structures: drawer type, fixed type, and plug-in type.

Drawer structure can accommodate up to 36 circuits.

Three-position switching of drawer circuits can be achieved without reducing the protection level.

Drawer movable parts are position-located and can match sound, light, and text indicators.

Comprehensive drawer-type electrical operation circuit solution.

The product has passed internal arc resistance tests, ensuring safe and reliable operation.

By combining intelligent components with an intelligent power distribution management system, intelligent monitoring and management are realized.
