Prices load switch load with load switch is off, a self-extinguishing function, overload protection function. Load switch and fuse combination usually Xi'an load switch, can automatically trip the circuit breaker with some functions (quick break and overcurrent). Load switch is mainly used in the opening and closing of distribution transformers and small capacity (<800KVA). Load switch by the fuse and isolating switch (or contacts) in series, in which the isolating switch (contactor) is responsible for opening and closing the loop normal current, the fuse is responsible for breaking the loop of all the non-normal current, including overload currents. Current fuse - operating time overcurrent curve ensures the action time.
