ZN63(VS1)-12 Series Side Mounted High Voltage Vacuum Circuit Breakers

Overview

ZN63(VS1)-12 series side-mounted high-voltage vacuum circuit breaker is an indoor high-voltage switchgear, suitable for a three-phase power system with a rated voltage of 12kV and a frequency of 50Hz. It is used as protection and control appliances. Due to the special advantages of vacuum circuit breakers , Especially suitable for places that require frequent operation at rated current, or break short-circuit current many times.

ZN63(VS1)-12 series side-mounted high-voltage vacuum circuit breaker adopts fixed installation and is mainly used for fixed switch cabinets. The circuit breaker can be used alone or in ring network power supply, box-type substations or various non-standard systems.
