1. The cabinet features an assembled design, while the circuit breaker is constructed with a floor-mounted handcart system.
2. It is fitted with a new composite insulated vacuum circuit breaker that offers excellent interchangeability and ease of replacement.
3. The handcart frame is equipped with a screw nut drive mechanism, which facilitates easy movement of the handcart and protects the drive structure from accidental damage.
4. All functionalities can be operated with the cabinet door securely closed.
5. The interlocking mechanism between the main switch, handcart, and cabinet door uses a forced mechanical locking system to fulfill the "five prevention" requirements.
6. The cable compartment is spacious enough to accommodate multiple cables.
7. A quick grounding switch is incorporated for grounding purposes and for closing short-circuit circuits.
8. The enclosure has an IP3X protection rating; when the handcart room door is open, the protection rating changes to IP2X.
9. This product adheres to the standards of GB3906-2006 and DL/T 404-2007, while also referencing the international standard IEC298.
