How Does A Circuit Breaker Work Step By

By | June 5, 2023



The circuit breaker is a critical component of any electrical system. It is the device that helps protect your home or business from dangerous overloads and short circuits, and it is essential for the safety of your wiring and appliances. But how does a circuit breaker work? Let's take a closer look at this crucial safety device.

At the heart of a circuit breaker is an electromagnet, which is a type of magnet that is activated by electricity. When the current flowing through the circuit exceeds a certain level, the electromagnet activates and triggers the circuit breaker to open. This cuts off the flow of electricity, preventing an overload or short circuit.

In addition to the electromagnet, a circuit breaker also contains a series of contacts, which are designed to conduct electricity when the circuit breaker is closed. When the current flowing through the circuit exceeds a certain level, these contacts open, breaking the circuit and preventing the electricity from flowing. The size of the contacts can be adjusted, allowing the circuit breaker to be tailored to the specific needs of the electrical system.

The circuit breaker is an essential safety device that can help protect your home or business from dangerous electrical surges and faults. Understanding how it works is an important part of keeping your electrical system safe and reliable. By taking the time to learn about circuit breakers, you can help ensure that your electrical system remains safe and functioning.
