In simple terms, it can be said that a fuse is a protective device used in electrical equipment and circuits so that when the flow exceeds the expectation of the device, the circuit is disconnected so that no other equipment is damaged. Miniature fuse uses two mechanisms for its operation: Bimetallic performance for overload protection and magnetic performance to protect short circuit. In other words, the detection of the excess flow is borne by a metal (bimetal). Which is heated by a current flow through the rated current and, by bending, causes the miniature fuse to contact and disconnects the circuit. The short-circuit current is also detected by a coil having a small number of circuits and large diameters, and a miniature fuse is detected.
Miniature fuses are categorized as highly sensitive to types B, Bright, C motor, D Transformer, K Power, Z Highly Sensitive:
Miniature fuse type B Lighting:
Type B miniature keys are commonly used in home lighting and lighting. These keys cut off the circuit during an overload between 3 and 5 times the nominal current at a specified time, and are suitable for normal home use. This key is also known as the Stealth Miniature Fuse.
Miniature Fuse Type C Motor:
C type miniature key is more industrial. These keys cut off the circuit during overload between 5 and 10 times the rated current at a specified time, and the cutoff time is greater than type B. This key is also known as the Flashing Miniature Fuse.
