Product Description

Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker: Embrace advanced technology with the ZN85-40.5kV, a leader in high-performance indoor vacuum circuit breakers.
Overview:

The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker is a breakthrough in three-phase AC 50Hz technology, boasting a rated voltage of 40.5kV. It integrates seamlessly into KYN61-40.5(Z) switchgear systems, representing the next generation of superior power supply and distribution solutions, engineered for unmatched efficiency and steadfast reliability in contemporary power infrastructures.

Revolutionary in design, this circuit breaker boasts an innovative upper and lower configuration that minimizes its depth, optimizing space without compromising performance. Encased within a sophisticated insulated tube are the vital components: the main conductive circuit, vacuum interrupter, and dynamic/static conductive connections. Its pioneering composite insulation structure distinctly segregates the three-phase arc-extinguishing chambers and electrified components, employing independent epoxy insulation casings to fulfill air gap and creepage distance norms under standard conditions. With all primary electrical connections steadfastly fixed, it guarantees supreme reliability and durability, ensuring peace of mind for all operations.
