A device that provides a continuous connection in case of overload is known as?

A device that provides a continuous connection in case of overload is known as a circuit breaker. Circuit breakers are designed to automatically interrupt electrical flow when they detect an overload or short circuit, preventing potential damage to the wiring and connected devices. They serve as protective devices that safeguard the entire electrical system by breaking the circuit when unsafe conditions arise, allowing for safe operation and easy reset once the issue is resolved.

Main switches are typically used for controlling the overall power supply to a system and do not protect against overloads in the same manner. Fuses also protect circuits from overloads but require replacement once they blow, rather than simply being reset. Surge protectors primarily protect against voltage spikes, not overload situations. Thus, the circuit breaker stands out as the most relevant choice for providing continuous connection and protection in the event of an electrical overload.
