Abstract

CJ12 series contactor used on the bridge crane usually appears breakdown,creates the main back circuit's short circuit and effects production.Replace EVS160-630 series low pressure vacuum contactor as CJ12 series contactor by modifing original control electric circuit, the result is fine and no breakdown,the production efficiency is increased.
