Introducing the state-of-the-art ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a pinnacle of modern engineering excellence. Operating at a three-phase AC 50Hz with a rated voltage of 40.5kV, it is the heart of the KYN61-40.5(Z) switchgear. This revolutionary power supply and distribution marvel is crafted for high performance and unwavering reliability, setting a new standard in contemporary power systems.
This innovative circuit breaker boasts a unique upper and lower arrangement, significantly reducing the device's depth for optimal space utilization. Encased within an insulated tube are the main conductive circuit, vacuum interrupter, and moving/static conductive connections, providing a robust and efficient solution. Its cutting-edge composite insulation structure ensures each of the three-phase arc-extinguishing chambers and their electrified components are distinctly separated by independent epoxy insulation casings. Designed to meet stringent air gap and creepage distance standards, all primary electrical connections are securely fixed, promising exceptional reliability and longevity.
