This series of vacuum contactors is designed for use in power networks with an AC frequency of 50Hz. 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 such as JDB electronic integrated protectors, JR9 type overcurrent protection devices, and resistance-capacitance absorbers. The main circuit rated voltage is 1140v, and the rated current can reach up to 630A. This contactor is particularly suitable 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 operation mechanism 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 needs.
