RS PRO 63 A British Standard Fuse, A4, 550 V AC, 94 mm

This 63 A fuse from RS PRO is suitable for use with general-purpose electrical equipment. Use it to protect your electrical system from short circuits and power surges. It's a high-rupture capacity (HRC) component, meaning it keeps both high and low fault currents from damaging your electrical circuits for improved power protection.


For fast and easy bolting to a fuse holder, the fuse comes with brackets fitted to either end. It's a long-lasting product that won't easily deteriorate, so there's no need to frequently change the fuses in your equipment. This fuse also increases the reliability of your electrical system thanks to its fast reaction in the event of a fault.


This fuse conforms to the Association of Short-Circuit Testing Authorities (ASTA) 20 standards for low-voltage fuses. You'll often find fuses of this type protecting devices such as motors, transformers and car wiring circuits.
