Product Description
General description

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

The contactor complies with 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 former is commonly used, but customers can choose the suitable type based on their specific application needs.
