What is A Blade Fuse?

A blade fuse features a plastic body and two metal prongs that are inserted into sockets. Also known as spade fuses or plug-in fuses, blade fuses are primarily used in automobiles, and can be mounted in fuse blocks, inline fuse holders, and fuse clips. Blade fuses come in a range of sizes and amp ratings, and are printed with the rated current (in amps) on top; many blade fuses use a common color-coding scheme for ease of identification.

WirthCo™ offers a variety of blade fuse options, including:

What is A Glass Tube Type Fuse?

A glass tube type fuse consists of a cylindrical glass cartridge with a thin metal wire running the length of the tube; the wire is connected to a metal cap at each end of the tube. All glass tube fuses are 1/4” in diameter. The length varies according to the ampere rating of the fuse, a design feature that prevents the insertion of an inadequate or unsafe fuse into the fuse panel.

There are two types of glass tube fuses: SFE and AGC. SFE glass fuses are available in 4 amp to 30 amp ratings; AGC glass fuses are available in 0.125 to 50 amp ratings

What is A Limiter Fuse?

Designed for currents over 40 amperages, a limiter fuse consists of a metal strip and a lock plate. Commonly used in forklifts, battery chargers, and similar applications, limiter fuses are frequently installed in close proximity to starter battery fuse boxes; special limiter fuses for automotive use are also available. These non-indicating stud-mount fuses help protect DC circuits against very high overloads and short circuits and avoid needless openings from starting currents and surges.

WirthCo™ stocks fast acting limiter fuses and automotive MiniDoc™ limiter fuses.
