Zi Kai Kyn28 12 Medium Voltage Vacuum Switchgear Feature
High reliability: KYN28-12 switchgear adopts vacuum circuit breaker as the main switch, with high breaking capacity and low cut-off value, which can effectively prevent the production of operating overvoltage and cut-off overvoltage, and improve the stability and reliability of the system.
Compact structure: The device adopts a middle structure design, making the overall structure compact and small footprint.
Easy operation: All operations are carried out in the closed state of the cabinet door, through the observation window can clearly see the position of the hand car in the cabinet and the status indication, easy and quick operation.
High protection level: the protection level of the shell reaches IP4X, and the protection level of the circuit breaker room is IP2X when the door is opened, which can effectively prevent debris and pests from invading the inside of the equipment and ensure the normal operation of the equipment.
