Circuit breakers are devices that automatically interrupt the flow of electricity in an electrical circuit. They are used to protect the circuit from damage caused by excessive current. There are two main types of circuit breakers: thermal-magnetic and electronic.

Thermal-magnetic breakers use a combination of heat and magnetism to trip the breaker, while electronic breakers use semiconductor devices to detect an overcurrent condition and then trip the breaker. Thermal-magnetic breakers are the most common type of breaker used in household and commercial applications. They are less expensive than electronic breakers, but they are not as fast at detecting and interrupting an overcurrent condition.

Electronic breakers are more expensive than thermal-magnetic breakers, but they offer a number of advantages. They are faster at detecting and interrupting an overcurrent condition, which minimizes the risk of damage to the circuit. Additionally, electronic breakers can be used in a wider range of applications since they are not limited by their voltage or current rating.

When selecting a circuit breaker, it is important to consider the voltage and current rating of the breaker, as well as the type of application it will be used in.
