Feature

● The switchgear adopts an assembled structure, and the circuit breaker adopts a floor-standing trolley (handcart) structure;

● Equipped with a brand-new composite insulated vacuum circuit breaker, which has the advantages of good interchangeability and easy replacement;

● The frame of the trolley is equipped with a screw nut pushing mechanism, which can easily move the handcart and prevent damage to the pushing structure due to misoperation;

● All operations can be performed with the switchgear door closed;

● The interlocking between the main switch, the trolley and the switchgear door adopts the mandatory mechanical locking method to meet the requirements of "five levels of protection";

● There is ample space in the cable room, which can connect multiple cables;

● Fast grounding switch is used for grounding and closing short circuit;

● The enclosure ingress protection rating is IP3X, when the trolley room door is open, the ingress protection rating is IP2X.
