This RS PRO British Standard size A1 fuse is designed to safeguard your circuits against high currents to prevent shorting. It's a bolted design, so you can easily secure and mount it to a fuse holder.

As this fuse is gG rated for general use, it'll typically blow within two to five seconds at five times the rated current, and within 0.1 to 0.2 seconds at ten times the rated current. It has a current of 20 A and voltage rating of 550 V AC. It also has a high rupturing capacity so it can withstand the high pressure developed during a short-circuiting situation.

This fuse is compliant with BS 88 and IEC 60269 specifications for British standard fuses and can be used in all kinds of domestic appliances. Part of the RS PRO series, it has been stringently tested by leading engineers.
