Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a masterpiece of modern electrical engineering. This three-phase AC 50Hz marvel, with a robust rated voltage of 40.5kV, is a pivotal component in KYN61-40.5(Z) switchgear systems. Engineered for unparalleled efficiency and steadfast reliability, it represents the new epoch of power supply and distribution technology, seamlessly integrating into contemporary power frameworks.

Revolutionize your circuit management with this circuit breaker, boasting a sophisticated upper and lower arrangement structure that trims the breaker depth. Within its insulated tube lies the main conductive circuit, vacuum interrupter, and dynamic/static conductive connections. The advanced composite insulation design ensures individual epoxy insulation casings separate the three-phase arc-extinguishing chambers and related components, meeting stringent air gap and creepage distance standards under regular conditions. Its fixed primary electrical connections cement its reputation for high reliability and enduring durability.

Key Features:

1. Composite Insulation Design: Masterfully meets the requirements for air gap and creepage distances while fine-tuning device dimensions. Its compact and judicious layout is not only efficient but also visually appealing.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, the mechanism harmonizes with the vacuum interrupter's characteristics, ensuring superior reliability, a prolonged lifespan, and a maintenance-free experience.
3. Flexible Handcart Design: Features an intuitive screw-rod push mechanism for seamless panel integration or removal. The forced mechanical interlock proficiently delivers "Five Prevention" functions, making it adaptable to a spectrum of operational settings, including demanding environments.
