What is a Load Break Switch?A load break switch is a control device equipped with a simple arc-extinguishing mechanism, capable of interrupting and closing circuits under load. It can interrupt a certain level of load current and overcurrent, but cannot interrupt short-circuit currents. Therefore, it must be used in series with a high-voltage fuse, relying on the fuse to clear short-circuit faults.Functions of a Load Break Switch:Interrupting and Making Function: Due to its limited arc-extinguis
