The KYN550-12 indoor armored removable type AC metal-enclosed switchgear (hereinafter referred to as the KYN550-12 switchgear) is the smallest-sized complete distribution equipment under our company, designed for 12kV three-phase AC 50Hz single busbar and busbar sectional systems.

The KYN550-12 features a “five prevention” interlocking function, which includes: preventing the circuit breaker trolley from being pushed or pulled under load, preventing incorrect opening or closing of the circuit breaker, preventing the circuit breaker from closing when the grounding switch is in the closed position, preventing accidental entry into the live compartment, and preventing the grounding switch from being mistakenly closed while energized. It is equipped with an indoor medium-voltage solid-sealed vacuum circuit breaker trolley, making it a high-performance distribution device.

The compact design of the KYN550-12 saves significant distribution space for customers and is primarily used in commercial and industrial buildings, real estate, data centers, and other industrial power grids that require miniaturized substations.
