Delivery Detail:30




KYN28A central metal-clad and metal-enclosed switchgear is produced independently based on the advanced manufacturing technique from home and abroad. It can be used to replace all sorts of old metal-enclosed switchgears.

The shell adopts the aluminum-zinc alloy coated steel sheet, processed by CNC machining tool, which ensure the high mechanical strength. The door is anti-corrosion and anti-impact coaedt. And the protection degree is IP4X

The main switch can be with the ZN63A (VSI) type of circuit breaker of this company, C3 series of fixed load switch; it is also with the interface communication.

The insulation distance is over 125mm, composite insulation is over 60mm. all the circuit breakers have the features of long working life, high parameters, less maintenance, small size and so on
