The VACG series AC M.V. vacuum contactor is designed for use in AC power systems with a frequency of 50Hz. It is suitable for main circuit rated voltages up to 12kv and rated currents up to 630A. This contactor is ideal for remote making and breaking, frequent starting, and controlling AC motors. It is particularly well-suited for use with fuses and a variety of protection devices, making it an excellent replacement for vacuum circuit breakers.
a. Environment temperature: -5ºC~+40ºC, and the average value is no more than +35ºC within 24 hours.
b. Altitude: no more than 1000m.
