Semiconductor Fuses
Need fuses urgently? We have a large range of semiconductor fuses in stock now
Fuses are one of the most commonly used protection components today. Fuses provide overload protection to a circuit, typically used in a plug to help to prevent damage by interrupting excessive current. Damage to a fuse is usually caused by short circuits, overloading, mismatched loads or a failure from the device. It is important that buyers and engineers choose the correct rating and type of fuse for the appliance to ensure ultimate protection and prevention of an electrical fire.
Our extensive range of semiconductor and industrial fuses will ensure your home or business keeps on functioning and your power supply is always available. Browse our collection of semiconductor fuses today, including battery storage fuses, British Standard BS88 fuses, cartridge fuses, cylindrical fuses, high speed fuses, high voltage fuses, low voltage fuses, NH DIN fuses, square body fuses, and fuse accessories.
We specialise in fuses from industry-leading manufacturers including Eaton Bussmann, Mersen and IXYS UK Westcode. We stock a large range of semiconductor fuses which are available on a same day or next day delivery service.
