Functions and Applications of Resettable Chip Fuses
Resettable chip fuses, also known as PTC (Coeficient de temperatură pozitiv) 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.

The fuse element is the part that melts due to excessive current flow in the circuit. The fuse element is made up of materials that have a low melting point and low ohmic losses like tin, lead, and zinc. Filling powder fills the internal space of the fuse body.

Protecția supracurentului | 5×20 6×30 mm Cartridge Fuses
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.
