Description

CHV-450/3.6(1.14) contactor has the same performance and function with Baker AC contactor, while it's more aligned with Chinese National Standards on some parameter index, contactor has independent drive with insolating function and the ability of breaking short time current. It has current/voltage mutual inductor which can realise the zero-current-break and comprehensive protection function; adopt quick pipe connection mode which is easy to use and maintain; highly integrated with small size and compact structure
