What happens to a Push Pull Circuit Breaker when it is overloaded?

When a Push Pull Circuit Breaker is overloaded, it functions as a safety device designed to protect the electrical circuit from damage. The correct response indicates that the breaker pops or trips to signal that it is open. This popping action physically moves the switch to the "off" position, interrupting the current flow. This interruption is crucial as it prevents overheating and potential damage to the circuit wiring or connected devices.

The design of this type of circuit breaker includes a mechanism that senses excessive current flow. When it detects a current level beyond its rated capacity, the internal mechanism activates, effectively disconnecting the circuit. After the breaker has tripped, it will typically have a visual indication (such as a popped button or a moved toggle) that shows it is in the open position, alerting users to the issue.

In contrast, options that imply it remains functional, melts, or requires tools to reset do not accurately describe the operation of a properly functioning Push Pull Circuit Breaker. The breaker must trip to ensure safety and prevent further complications in the system.
