Circuit Breaker

The circuit breaker is designed for automatic operation of electrical switches to protect the overload or short circuit that may cause damage to the circuit. Its basic function is to detect fault conditions and stop the current immediately by interrupting continuity. Unlike a fuse that has been used once and then needs to be replaced, the circuit breaker can be reset (manually or automatically) to resume normal operation. The circuit breakers are divided into different sizes. They can protect the switches of personal household appliances. The large ones are designed for high-voltage lines to protect the whole city.
