KYN28-12 Metal-Enclosed Withdrawable Switchgear (12 kV)
Indoor 3.6–12 kV three-phase 50/60 Hz single-busbar and sectioned-busbar systems air-insulated, metal-enclosed withdrawable switchgear—HARRL's flagship medium-voltage cabinet and its most widely deployed model. The cabinet is divided into four separate compartments (busbar, circuit breaker, cable, and low-voltage), each equipped with pressure relief channels for arc exhaust, along with five-fold mechanical interlocks to prevent misoperation. It accommodates VS1 / ZN63A-12 (or equivalent) withdrawable vacuum circuit breakers; supports wall-mounted and back-to-back arrangements.
