VCF series vacuum contactors

VCF series vacuum contactors VCF type drawable Vacuum Contactor-Fuse Combinations (also called F-C circuit) is new type apparatus. With the help of the short circuit protection HV fuse and the frequently operated vacuum contactor, VCF® would be expert in controlling and protection for MV motors, transformers, and capacitors, etc. Processed with the technology of unique embedded pole by epoxy resin APG process.
