This strip is made up of two different metals with different expansion rates. When the current flowing through the circuit exceeds the breaker’s rating, the heat generated causes the bimetallic strip to bend. This bending action triggers the breaker to trip, opening the circuit and stopping the flow of electricity.
Once the circuit breaker has tripped, it needs to be manually reset. This can be done by flipping the breaker switch back to its original position. However, it’s important to identify and address the cause of the overload or short circuit before resetting the breaker. If the issue persists, it may indicate a more serious problem that requires professional attention.
