Product Description

General description

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.

The VACG series AC M.V. vacuum contactor conforms to GB/T 14808, IEC 60470, and JB/T 7122 standards. Its main performance indicators have reached international levels, ensuring its reliability and safety. This product is also known as the 6kv 10kv Medium Voltage Vacuum Contactor for Capacitor Switchgear and is commonly referred to as a vacuum contactor, medium voltage contactor, or capacitor contactor.
