Vacuum Contactor HVJ6 from JUCRO Electric
HVJ6-7.2 series indoor high-voltage AC vacuum contactor has two types: One is Mechanical holding type, the other is Electromagnetic holding type. It is applicable for three-phase AC 50HZ power system of rated voltage 7.2KV and below and rated current up to 630 A to open and close circuit remotely and control electrical equipment like high-voltage motor, transformer and capacitive load. It is especially suitable for fields operated frequently. The contactor uses the international fashionable up and down structure arrangement and has the advantages of small, light, easy to maintain and form a complete set of F-C circuit equipment.
