RS PRO 25A British Standard Fuse, A1, 550V ac, 44.5mm

RS PRO 25 A British Standard Fuse, A1, gG, 550 V AC

If you need to protect your electrical setup from harmful power surges or short circuits, use this fuse from RS PRO. There are brackets on both ends, so you can easily bolt it to a fuse holder.


This fuse won't easily deteriorate, meaning there's no need for frequent replacement. For enhanced power protection, it has a high rupture capacity (HRC) that prevents both low and high fault currents from damaging electrical circuits. Thanks to its quick reaction time in the event of a fault, it's a highly reliable component.


A fuse like this one is frequently used to protect car circuitry, transformers and motors. It conforms to ASTA 20 (Association of Short-Circuit Testing Authorities) standards for low-voltage fuses.
