The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker is a cutting-edge three-phase AC 50Hz unit with a robust rated voltage of 40.5kV. Seamlessly integrated within KYN61-40.5(Z) switchgear, it heralds a new era of power supply and distribution with its state-of-the-art design focused on delivering superior efficiency and unparalleled reliability, perfectly tailored for the sophisticated demands of modern power systems.
This circuit breaker showcases an innovative upper and lower arrangement, ingeniously decreasing the device's depth. Encased within an insulated tube are its main conductive circuit, vacuum interrupter, and dynamic/static conductive connections. Its ground-breaking composite insulation structure individually segregates the three-phase arc-extinguishing chambers and associated electrified components with distinct epoxy insulation casings, fully compliant with air gap and creepage distance standards in typical scenarios. With all primary electrical connections steadfastly fixed, it ensures exceptional reliability and longevity.
