The KYN28A-12 indoor AC metal-clad withdrawable switchgear (hereinafter referred to as switchgear) is a complete set of power distribution devices of 3.6kV ~ 12kV three-phase AC 50Hz single bus or single bus sectional system

The switchgear is mainly used in power plants, small- and mediumsized power generators, industrial and mining enterprises, and secondary substations of power system for power receiving, power transmission, and startup of large-sized high-voltage motor in order to implement control, protection, and monitor.

The switchgear complies with IEC62271 and GB3906 standards and comes out with a variety of protection functions,including preventing pulling or pushing circuit breaker handcart in load mode,preventing turning on/off the circuit breaker by mistake, preventing turning on the circuit breaker when the grounding switch is in ON position, preventing entering the energized cubicle by mistake, and preventing turning on the interlock function of the grounding switch by mistake in energized state.

The switchgear can be used in conjunction with the VD4 circuit breaker of the ABB company, VS1 circuit breaker, isolation handcart, and voltage transformer. It is really a high-performance power distribution device.
