Product Description

General description

This series of vacuum contactors is designed to cater to power networks with an AC frequency of 50Hz. The main circuit rated voltage is 1140v, and the rated current can go up to 630A. It is ideal for making, breaking, frequently starting, and controlling AC motors. Additionally, it can be used to form a magnetic starter with a variety of protection devices, such as the JDB electronic integrated protector, JR9 type over current protection device, and resistance-capacitance absorber. This vacuum contactor is particularly suitable for forming an anti-explosion magnetic starter.

The contactor conforms to IEC 60947-4-1, GB/T 14048.4, and JB/TN 7122 standards. Its main performance indicators have reached the international level, making it a reliable and efficient choice for various applications. This product is available in two operation mechanism types: coil operation mechanism type and permanent magnet operation mechanism type. The coil operation mechanism type is the most commonly used, but customers can choose the suitable type according to their specific application needs.
