Structural Features

● The cabinet structure is assembled, and the circuit breaker adopts a grounded handcart structure.

● Equipped with a brand new type of composite insulation vacuum circuit breaker, featuring good interchangeability and can be easily replaced.

● The handcart frame is equipped with a screw and nut propulsion mechanism, allowing easy movement of the handcart and preventing accidental damage to the propulsion structure

● All operations can be performed with the cabinet door closed. The interlocking between the main switch, handcart, and switchgear door adopts a mandatory mechanical interlock method to meet the "five prevention" function.

● The cable compartment has ample space and can accommodate the connection of multiple cables.

● The fast grounding switch is used for grounding and circuit short-circuit.

● The enclosure protection level is IP4X, and with the door open, the protection level is IP2X.
