The KYN28-12 armored removable AC metal-enclosed switchgear is designed for 3.6-12kV three-phase AC 50Hz power grids. It is primarily used to receive and distribute electrical energy while providing control, monitoring, and protection for the circuit. This versatile system is compatible with single busbar, single busbar segmentation, or double busbar systems.

The enclosure is fully assembled with bolts, providing high mechanical strength and a neat appearance. The cabinet door is plastic-sprayed for enhanced impact and corrosion resistance. It can be equipped with various vacuum circuit breakers including VD4, VS1, VH1, VK, and ZN28, ensuring an air insulation distance of over 125mm.

* Note: Avoid fire, explosion hazards, serious pollution, chemical corrosion, and severe vibration.
