KYN28-12 Metal-Clad Withdrawable Switchgear (12 kV)
Air-insulated, metal-clad withdrawable switchgear for indoor 3.6–12 kV, three-phase 50 / 60 Hz single-busbar and sectionalized-busbar systems — HARRL's workhorse MV cabinet and the most widely deployed model in the range. The enclosure is divided into four independent compartments (busbar, circuit-breaker, cable and low-voltage), each fitted with a pressure-relief channel for arc venting, and a five-prevention mechanical interlock guards against misoperation. Accepts VS1 / ZN63A-12 (or equivalent) withdrawable vacuum circuit breakers; supports wall-mount and back-to-back arrangements.
