【Reliable Switching Solution for Single Busbar Systems】
Do you need a switchgear system centered on a high-performance circuit breaker? Our KYN28A-12 metal-enclosed interrupter switchgear is designed for this purpose. It is suitable for 3.6–12kV, three-phase AC 50Hz single busbar systems and serves as a complete power distribution unit.

It is widely used for auxiliary power supply in power plants, factory distribution systems, secondary substations, and for starting high-voltage large motors. The unit provides functions for power control, protection, and system monitoring.

【Enhanced Safety with Five Anti-Misoperation Interlocks】
This metal-enclosed interrupter switchgear is equipped with five anti-misoperation interlocking functions to ensure operational safety:

Prevents racking the circuit breaker in or out under load

Prevents accidental closing or opening of the circuit breaker

Prevents closing the circuit breaker when the earthing switch is closed

Prevents entry into energized compartments

Prevents closing the earthing switch when the system is live

These safety mechanisms significantly reduce operational risks and improve system reliability.
