Product Description

Product Description

 ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker is a three-phase AC 50Hz device with a rated voltage of 40.5kV. Widely used in KYN61-40.5(Z) switchgear, it is a new generation of power supply and distribution equipment designed for high efficiency and reliability in modern power systems.

This circuit breaker features an upper and lower arrangement structure, effectively reducing the depth of the breaker. The main conductive circuit, vacuum interrupter, and moving/static conductive connections are housed within an insulated tube. Its advanced composite insulation structure separates the three-phase arc-extinguishing chambers and the associated electrified components with independent epoxy insulation casings, meeting air gap and creepage distance requirements under normal conditions. All primary electrical connections are fixed, ensuring high reliability and durability.

Key Features:

1. Composite Insulation Design: Ensures compliance with air gap and creepage distance requirements while optimizing device dimensions. The layout is compact, rational, and aesthetically pleasing.
2. Innovative Operating Mechanism: Specially designed for this vacuum circuit breaker, the mechanism matches the characteristics of the vacuum interrupter, offering high reliability, extended lifespan, and maintenance-free operation.
3. Flexible Handcart Design: Incorporates a screw-rod push mechanism for easy panel insertion or withdrawal. Equipped with a forced mechanical interlock to achieve "Five Prevention" functions, making it suitable for various operational environments, including harsh conditions.
