KYN28A-24 Armored Removable AC Metal- Enclosed Switchgear
The busbar system features a single-bus configuration, which can be adapted to single-bus-with-bypass or double-bus structures. It enables the execution of various switching operations while the high-voltage compartment door remains closed. It features a compact structure and flexible layout options, thereby minimizing floor space requirements. With the door closed, the enclosure achieves an IP4X protection rating, effectively ensuring personnel safety. It incorporates a "Five-Prevention" interlocking mechanism to safeguard the operating personnel. The cable compartment offers ample space, facilitating the installation of multiple cables as well as equipment maintenance. It offers flexible options for the selection of vacuum circuit breakers.
