KYN28A-12 Indoor AC Metal-Clad Withdrawable Switchgear


Product Introduction:

This switchgear is equipped with a VS1 or VD4 vacuum circuit breaker featuring high breaking capacity and low chopping current. It has reliable “five-prevention” interlocking functions: preventing misoperation, preventing the truck from being pushed in or pulled out under load, preventing the circuit breaker from being closed when the earthing switch is closed, preventing the earthing switch from being closed while energized, and preventing accidental entry into energized compartments. It is a power distribution unit with excellent performance.


Product Features:

The design, manufacture, and components of this switchgear comply with International Electrotechnical Commission (IEC) standards and Chinese national (GB) standards, fully considering customer requirements for simplicity, reliability, and safety.

Clear prompts and simple, easy operation.

All operations are performed from the front.

On-site setting of intelligent controller parameters.

Only simple routine operation checks and cleaning maintenance are required; lubrication is needed once every five years.
