Product Detail

Vacuum Interrupter 1.14KV 630A HCJ5 for vacuum contactor from JUCRO Electric


Brief introduction

The vacuum interrupter adoption porcelain and ceramics makes to insulate the outer shell. Contact is WCCu metal alloy material advanced technique of adoption Including bulk small. Breaking the abiliting strong the life span is long, maintenanle is simple, no explosion dangerous, no contaminate and the noise is low. It is extensive to used for coal mine , chemical engineering, Petroleum metallurgy etc. department, more than keeping with at the multifarious operation with the bad place usage of environment
