The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker is a cutting-edge three-phase AC 50Hz device, engineered with a rated voltage of 40.5kV. It is extensively utilized in KYN61-40.5(Z) switchgear systems. As a state-of-the-art solution, this generation of power supply and distribution equipment has been meticulously crafted to deliver exceptional efficiency and unwavering reliability in contemporary power systems.
This remarkable circuit breaker boasts an innovatively designed upper and lower arrangement structure, substantially minimizing the breaker's depth. Enclosed within an insulated tube are the main conductive circuit, vacuum interrupter, and moving/static conductive connections. Its sophisticated composite insulation arrangement effectively separates the three-phase arc-extinguishing chambers from associated electrified components, all housed in independent epoxy insulation casings to meet air gap and creepage distance standards under standard conditions. With all primary electrical connections being fixed, this design ensures superior reliability and long-lasting durability.
