What Are The Function Of Circuit Breaker

By | May 3, 2023



Circuit breakers are a vital component of any electrical system, offering protection against short circuits and overloads. They are designed to automatically shut off the power supply when an unsafe situation is detected, preventing damage to both people and equipment. But what do circuit breakers actually do?

First, circuit breakers help protect against electrical fires caused by short circuits or overheating. When a short circuit occurs, a large amount of electricity flows through the wiring, causing it to overheat. The circuit breaker senses this, and shuts off the power before the wiring can become damaged or ignite. This is especially important in areas with aging wiring, as a circuit breaker can prevent a potentially deadly fire.

Second, circuit breakers help protect against overloaded circuits. If too much current is flowing through a circuit, the device can trip and shut off the power, preventing further damage. This is especially important for appliances that draw a lot of power, like air conditioners and refrigerators, as an overloaded circuit can cause them to malfunction or even catch fire.

Finally, circuit breakers act as a safeguard against electrical shocks. When an overload or short circuit occurs, a circuit breaker will trip and prevent electricity from reaching people or objects. This is why it’s important to install a circuit breaker near wet areas or areas where children and pets may be present.

In conclusion, circuit breakers are essential components of any electrical system, providing protection against electrical fires, overloads and dangerous shocks. By understanding their functions, you can ensure your home and family are safe from electrical hazards.
