VHC/VHCR Withdrawable Vacuum Contactors and Fuse Combinations
Vacuum contactors and contactor-fuse combinations for repeated load switching, selected by load duty, operating frequency and protection coordination.
Technical Description
The VHC/VHCR family includes contactors and contactor-fuse combinations for repeated switching of specified loads. Identify motor or other load characteristics, operating frequency, holding arrangement, control supply and withdrawable interfaces. Define the contactor, carriage, fuses and auxiliaries as separate supply items. Short-circuit performance of a protected combination depends on its coordination and must not be attributed directly to the contactor alone. Electrical data must apply to the selected contactor and coordinated fuse configuration.
