RS PRO 4A British Standard Fuse, F1, 550V ac

This general-purpose fuse from RS PRO is a reliable choice to protect your electrical equipment from power surges and short circuits. It's a high rupture capacity (HRC) component, which assures you optimal power protection by preventing high bursts of current from damaging electrical circuits.


The fuse has a blade tag extending from the ends of its cap for mounting to a holder. It's unlikely to deteriorate over time, meaning you won't need to change it frequently. As it reacts quickly to any faults in your electrical circuit, it enhances the reliability of your system.


Fuses such as this one are often used to protect devices like transformers and motors, as well as car wiring circuits. This product meets ASTA 20 (Association of Short-Circuit Testing Authorities) standards of quality and safety for low-voltage fuses.
