[0002] A load switch is an electrical appliance whose function is between that of a high-voltage circuit breaker and a high-voltage disconnecting switch. High-voltage load switches are often used in series with high-voltage fuses; they are used to control power transformers. High-voltage load switches have a simple arc extinguishing device, so they can switch on and off a certain load current and overload current. However, they cannot disconnect short-circuit current, so they are generally used in series with high-voltage fuses to achieve short-circuit protection by means of fuses.
