What are gang-operated switches primarily used for?

Gang-operated switches are primarily used to break load and open all three phases simultaneously in a three-phase electrical system. This capability is crucial because it ensures that the entire circuit is de-energized safely when maintenance or repairs are needed. By operating all three phases together, gang-operated switches minimize the risks associated with single-phase operations, such as electrical imbalances or the potential for equipment damage due to partial disconnection.

This functionality is particularly important in industrial and utility applications where safety and reliability are paramount. It enables personnel to maintain or service electrical equipment without exposing them to live wires and ensures that electrical systems can be safely managed in a coordinated manner. The simultaneous action improves operational efficiency and enhances safety protocols during maintenance activities.

While connecting multiple circuits, redirecting electricity, or monitoring electrical loads are essential functions of different types of switches or devices in power distribution, they do not capture the primary purpose of gang-operated switches as effectively as the ability to break load on all phases at the same time.
