Electronic fuses (шпора) are solid-state devices that protect electronic circuits from overcurrent conditions. Unlike traditional fuses, they can be electronically reset, offering a more convenient and efficient solution for circuit protection. eFuses protect against short circuits, overloads, and other fault conditions, preventing damage to devices and wiring.

Resettable chip fuses, also known as PTC (Положителна температурна коефициент) resettable fuses or PPTC (Polymeric Positive Temperature Coefficient) devices, are circuit protection components that automatically reset after a fault condition is cleared. They protect against overcurrent and over-temperature situations, offering a self-resetting solution that enhances reliability and reduces downtime in various applications.

An overcurrent protection electrical fuse is a safety device that interrupts the flow of electricity in a circuit when the current exceeds a predetermined level. It acts as a sacrificial link, melting and breaking the circuit to prevent damage to wiring and other components from overheating or potential fires due to excessive current.
