Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a sophisticated three-phase AC 50Hz device that boasts a rated voltage of 40.5kV. Specifically designed for integration into KYN61-40.5(Z) switchgear, this innovative equipment represents a new era of power supply and distribution, engineered to deliver high efficiency and unparalleled reliability for the demands of contemporary power systems.
This state-of-the-art circuit breaker showcases an ingeniously designed upper and lower arrangement structure, significantly minimizing the breaker's depth for a streamlined profile. The main conductive circuit, along with the vacuum interrupter and dynamic/static conductive connections, are expertly encased within a durable insulated tube. Its cutting-edge composite insulation structure elegantly isolates the three-phase arc-extinguishing chambers and related electrified components, utilizing independent epoxy insulation casings that rigorously fulfill air gap and creepage distance standards under standard operational conditions. The fixed nature of all primary electrical connections guarantees exceptional reliability and longevity.
