ZN 63
Adopting advanced vacuum arc extinction technology, the breaker features strong breaking capacity and stable insulation performance. It achieves arc-free operation, low noise and pollution-free work, supporting frequent switching operations.
Configured with a high-stability spring operating mechanism, ZN63 runs flexibly and stably with low mechanical wear. It can quickly cut off short-circuit faults, ensuring high operational reliability and long service life.
With compact modular structure and high mechanical strength, the product occupies small installation space and adapts to various complex indoor power supply scenarios.
It is easy to install and debug with minimal daily maintenance, effectively reducing long-term operation costs for power distribution projects.
As classic core protection equipment for 12kV power systems, ZN63 vacuum circuit breaker delivers stable performance and high safety. We provide global customers with factory direct supply, complete certifications and professional after-sales service.
Product Details
Overview
ZN63A (VS1)-24 indoor high voltage AC vacuum circuit breaker (hereinafter referred to as circuit breakeris used in three-phase AC 50Hz indoor places with rated voltage of 24kV. It is suitable for applications withloads of different nature and freguent operations for the protection and control of electrical facilities used inindustrial and mining, enterprises, power plants and substations, especially for metallurgy, chemicals, andcoal industries.
The circuit breaker comply with GB/T 1984 "High-voltage alternating-current circuit-breakers", GB/T 11022"Common specifications for high-voltage switchgear and controlgear standard", DL/T 402 "High-voltagealternating-current circuit-breakers", and IEC standard.
The operating mechanism of circuit breaker is designed as an integrated structure. The operating mechanismand the primary circuit are arranged at front and back. It can be used as a fixed installation unit (hixed cabinetor form a handcart unit (handcart cabinet) together with the advance mechanism (chassis cart)
