ZN 63

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)
