Load Break Switch is an electrical switching device specifically designed to safely disconnect or close a circuit that is carrying an electrical load under normal operating voltage conditions. Unlike a basic isolator switch, which can only be operated when there is no current flowing, the load break switch incorporates features like arc chutes or magnetic blowout coils to extinguish the electrical arc that forms when its contacts separate under load current. However, a crucial distinction is that while it can handle normal load currents, it is not designed or rated to interrupt high fault currents (like short circuits), a capability reserved for circuit breakers. Therefore, load break switches are commonly used in medium-voltage applications, such as switchgear panels, for tasks like isolating transformers, motors, or generator sets for maintenance or operational reconfiguration, providing a convenient way to de-energize equipment without relying on a protective device.

in this line since 1972 We are manufacturer, dealers and exporters of Load Break Switch (LBS) in ahmedabad, gujarat, india. Load break switches play a vital role in ensuring the safety and reliability of electrical systems by allowing operators to isolate circuits for maintenance, reconfiguration, or emergency situations.

Load Breaking : This is its primary function. Unlike a simple isolator switch (which can only open a circuit when there is no load current flowing), a load break switch has features (like arc chutes or blowout coils using magnetic fields) to extinguish the electrical arc that forms when the contacts separate under load.
Closing Under Load : It can also close (connect) a circuit that might be energized on one side, again handling the associated arcing.
Not a Circuit Breaker : While it can open a circuit under load, it is not a circuit breaker. It does not have the ability to interrupt fault currents (like short circuits or ground faults) which can be many times higher than normal load current. Interrupting fault currents requires much more robust arc suppression and thermal/mechanical capacity.
Not an Isolator (Typically) : While it provides some level of isolation, it's generally not rated for safe personnel access or maintenance in the same way a dedicated isolator (or disconnect switch) is, which is designed to withstand higher voltages across the open contacts when the circuit is de-energized. Some load break switches might have an isolator function as well (making them Load Break Isolator switches), but the core capability is load breaking.
