Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Discover the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a pinnacle of three-phase AC 50Hz technology with a commanding rated voltage of 40.5kV. Perfectly integrated into the KYN61-40.5(Z) switchgear, this cutting-edge equipment signifies the next era of high-efficiency and highly reliable power supply and distribution for modern power systems.

Engineered with an innovative upper and lower arrangement structure, this circuit breaker significantly minimizes its depth. The insulated tube securely encases the main conductive circuit, vacuum interrupter, and moving/static conductive connections. Our advanced composite insulation structure distinctively separates the three-phase arc-extinguishing chambers and electrified components, with individual epoxy casings that adhere to air gap and creepage distance requirements. Every primary electrical connection is immovably fixed to ensure unrivaled reliability and durability.

Key Features:

1. Composite Insulation Design: Ensures full compliance with air gap and creepage distance norms while offering an optimized, compact, and visually appealing device layout.
2. Innovative Operating Mechanism: Designed uniquely for this vacuum circuit breaker, it perfectly synchronizes with the vacuum interrupter's characteristics, delivering exceptional reliability, prolonged service life, and a maintenance-free experience.
3. Flexible Handcart Design: Incorporates a highly efficient screw-rod push mechanism for effortless panel insertion or removal. It boasts a robust mechanical interlock to ensure the 'Five Prevention' functions, making it ideal for diverse and challenging environments.
