Product Advantages
Rugged Structure & Easy Maintenance
The frame utilizes Al-Zn coated steel sheets with double-bending technology, combining high strength and corrosion resistance with superior stability. The top cover of the horizontal busbar area is removable, facilitating easy installation, inspection, and later maintenance of the busbars.
Versatile & Adaptable Functional Units
Covering withdrawable, removable, and plug-in functional units, it flexibly matches the needs of diverse power distribution scenarios. The compact withdrawable structure allows for up to 36 circuits, drastically maximizing space utilization.
Safe & Intuitive Operation
The withdrawable circuit supports three-position conversion without reducing the protection rating during the process, ensuring operational safety. The removable components of the drawer feature a precise positioning function, paired with triple acoustic, optical, and textual indications for clear and identifiable status.
Comprehensive & Reliable Control Schemes
Provides complete motor-operated drawer circuit solutions to seamlessly meet automated control and remote operation needs, perfectly adapting to diverse application scenarios.
