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, with a rated current of up to 630A. These contactors are suitable for making, breaking, frequently starting, and controlling AC motors. They can also be used to form magnetic starters with a variety of protection devices, including the JDB electronic integrated protector, JR9 type over current protection device, and resistance-capacitance absorber. These contactors are particularly well-suited for forming anti-explosion magnetic starters.

The contactors conform to IEC 60947-4-1, GB/T 14048.4, and JB/TN 7122 standards, and their main performance indicators have reached international levels. The "Y" designation indicates that this product is available in both 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.
