RS PRO 5A FF Ceramic Cartridge Fuse 5 x 20 mm, 250V AC, Super Fast Acting, Ceramic Body 420-117

RS PRO 420-117 is a 5A FF (super fast acting) ceramic cartridge fuse with dimensions of 5 x 20 mm and a rated voltage of 250V AC. The ceramic body provides excellent insulation and can withstand higher operating temperatures ensuring reliable circuit protection.

This ultra-rapid fuse type is particularly suitable for protecting semiconductor devices such as thyristors, diodes, and transistors from overcurrent or short circuit conditions by acting quickly to prevent damage.

The fuse is cylindrical in shape with a compact 5 mm diameter and 20 mm length, fitting standard 5 x 20 mm fuse holders used in a wide variety of applications.

Its high breaking capacity (HBC) rating ensures that the fuse can safely interrupt large fault currents without rupture or explosion, providing durable protection for sensitive electrical components.

Typical use cases include safeguarding electrical appliances like motors, air conditioning units, refrigerators, pumps, and other industrial, commercial, residential, and automotive electrical equipment.

Compared to circuit breakers, fuses such as this one react faster to faults and are less expensive, although they require replacement after operation. Rated current: 5 amperes at 250 volts AC. Super fast acting (FF) characteristic for rapid protection.

Ceramic body assures high-temperature tolerance and durability. Standard fuse size: 5 mm diameter by 20 mm length. UL and RoHS compliant for quality and safety assurance. High breaking capacity suitable for high fault current scenarios.

Ideal for industrial, commercial, automotive, and residential protection needs. Easy to replace in compatible fuse holders.
