Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Meet the ZN85-40.5/T(3AV3), an indoor handcart vacuum circuit breaker crafted for peak performance in modern energy systems. This three-phase AC 50Hz marvel, boasting a rated voltage of 40.5kV, integrates seamlessly with KYN61-40.5(Z) switchgear. It's setting new standards in power supply and distribution with its high-efficiency design and unmatched reliability.

With a smart upper and lower configuration, this circuit breaker minimizes depth while housing its key components—the main conductive circuit, vacuum interrupter, and moving/static conductive connections—safely within an insulated tube. Its cutting-edge composite insulation structure, featuring independent epoxy insulation casings, ensures compliance with air gap and creepage distance standards. This not only enhances safety but also guarantees exceptional durability and reliability through fixed primary electrical connections.

Key Features:

1. Composite Insulation Design: This innovative design ensures the breaker meets all air gap and creepage distance specifications, while its compact, rational arrangement adds a touch of aesthetic elegance.
2. Innovative Operating Mechanism: Tailor-made for this vacuum circuit breaker, the mechanism aligns perfectly with the vacuum interrupter's characteristics, providing stellar reliability, an extended operational life, and a maintenance-free experience.
3. Flexible Handcart Design: Equipped with a screw-rod push mechanism, this design ensures effortless panel insertion or removal. The added forced mechanical interlock bestows it with 'Five Prevention' capabilities, making it robust enough for any operational environment, including extreme conditions.
