Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, an innovative three-phase AC 50Hz marvel with a rated voltage of 40.5kV. This cutting-edge device is extensively employed in KYN61-40.5(Z) switchgear. As a next-generation power supply and distribution solution, it is engineered for optimal performance, exceptional efficiency, and unwavering reliability in contemporary power systems.
This remarkable circuit breaker boasts a unique upper and lower arrangement structure that significantly minimizes its depth. Encased in an insulated tube are the main conductive circuit, vacuum interrupter, and both moving and static conductive connections. Its state-of-the-art composite insulation architecture distinctly isolates the three-phase arc-extinguishing chambers with dedicated epoxy insulation casings, ensuring compliance with air gap and creepage distance norms under standard conditions. The fixed nature of all primary electrical connections guarantees superior reliability and longevity.
