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.
