This switchgear complies with :GB/T11022-1999, GB3906-1991, and DL/T404-1997.
The cabinet structure is of an assembled type, with the circuit breaker adopts a handcart floor-mounted design.
Optional components include:
* Chinese design vacuum circuit breaker ZN85-40.5(3AV3)
* Xiamen Huadian sealed vacuum circuit breaker VEP-40.5
These similar circuit breakers are interchangeable.
The handcart frame is equipped with a screw-nut advancing mechanism and an overrun clutch, which allows for easy movement of the handcart and prevents damage to the advancing mechanism due to incorrect operation.
The interlocking between the grounding switch, the retraction of the cart, and the switchgear is all implemented through a mandatory mechanical interlocking method, meeting the "five protections" interlocking function.
