Load Break Switch
Load Break Switch is a mechanical switching device designed to safely make, break, and carry rated load currents in medium-voltage circuits. It provides reliable on/off control and visible isolation for transformers, feeders, and capacitor banks, but is not rated to interrupt fault currents.
Commonly used in distribution networks and industrial power systems, it supports flexible circuit reconfiguration and enhances operational safety by providing a clear, physical disconnect point during maintenance or system adjustments.
