National power industries is leading certified manufacturer exporter and suppliers of load break switch in Vadodara, Surat, Vapi, Valsad, South Gujarat, India, load break switch (LBS) is a mechanical switching device used in medium-voltage electrical distribution systems to connect or disconnect circuits under load conditions. Unlike isolators, which can only be operated when the circuit is de-energized, load break switches are designed to safely interrupt the flow of current during normal operating conditions. They incorporate arc-extinguishing mechanisms, such as SF6 gas, vacuum, or air, to safely manage the arc that forms when the switch opens under load. Commonly found in ring main units and switchgear assemblies, load break switches provide a reliable and cost-effective means of isolating parts of the electrical network for maintenance or fault isolation. Though they do not interrupt fault currents like circuit breakers, they play a critical role in ensuring operational safety and continuity in medium-voltage power distribution.
