diff types of fuses
Fuse (automotive) Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. They are occasionally used in non-automotive electrical products. Glass & Ceramic Tube Fuses Generally, two sizes of user-replaceable fuses are found: the 1/4â x 11/4â and 5 x 20mm. Each is available in a variety of volt and amp ratings. Fuse Types. There are two basic types of fuses available for appliances and consumer electronics: fast-acting or time-delay. Any replacement fuse must match the one itâs replacing. In general, fast-acting fuses are a single strand of wire or strip of metal. Time-delay fuses usually have a coiled wire, a thick element wrapped in wire, or a spring. Most electronic fuses will have the voltage and amp rating stamped on the end cap. The type of fuse can generally be visually identified. Also, ownerâs manuals will have the correct replacement fuse generically identified. For example: âUse a 2 amp, time-delay, 250 volt fuse.â Glass and ceramic tube fuses vary by diameter and length:
