VHL/VHLR-12 Withdrawable Vacuum Load Switches and Fuse Combinations
The VHL/VHLR-12 family covers load switches and switch-fuse combinations, with switching duties and coordinated protection assigned to the specific configuration.
Technical Description
This family includes withdrawable vacuum load switches and switch-fuse combinations. Each model suffix must be linked to its actual switching configuration. Check carriage travel, primary contacts, secondary connectors, interlocks and the operating supply, then select fuses against the load and protection requirements. Define the switching device, carriage, fuses and auxiliary contacts supplied. The switching duties of the standalone device and the coordinated fuse combination must be confirmed separately.
