Introducing the ZN85-40.5/T(3AV3), an exceptional indoor handcart vacuum circuit breaker operating at three-phase AC 50Hz with a rated voltage of 40.5kV. Perfectly engineered for KYN61-40.5(Z) switchgear, this cutting-edge equipment represents the new era of power supply and distribution. It is meticulously designed to deliver unparalleled efficiency and reliability in the sophisticated realm of modern power systems.
This revolutionary circuit breaker showcases an ingenious upper and lower arrangement structure, significantly minimizing the breaker’s depth. Within an expertly insulated tube reside the main conductive circuit, vacuum interrupter, and moving/static conductive connections. Its state-of-the-art composite insulation structure ingeniously isolates the three-phase arc-extinguishing chambers and related electrified components using distinct epoxy insulation casings, flawlessly meeting air gap and creepage distance standards. All primary electrical connections are firmly secured, promising remarkable reliability and longevity.
