Product Description

General description

This series of vacuum contactors is designed for use in power networks with an AC frequency of 50Hz. The main circuit is rated for a voltage of 1140v and a current of up to 630A. It is suitable for making, breaking, frequently starting, and controlling AC motors, as well as for forming magnetic starters with a variety of protection devices, including the JDB electronic integrated protector, JR9 type over current protection device, and resistance-capacitance absorber. This contactor is particularly well-suited for forming anti-explosion magnetic starters.

The contactor conforms to IEC 60947-4-1, GB/T 14048.4, and JB/TN 7122 standards, and its main performance indicators have reached international levels. The product is available in two types: coil operation mechanism type and permanent magnet operation mechanism type. The coil operation mechanism type is typically used, but customers can choose the suitable type according to their specific application.
