Safeguard against short-circuits with this British Standard size 4A fuse from the RS PRO range that protects against high currents. This fuse has a gG rating so it's suitable for general use and will usually blow from two to five seconds at five times the rated current, and within 0.1 to 0.2 seconds at ten times the rated current.

The fuse is bolted so you can easily attach and mount it to your fuse holders. It has a current rating of 100 A with a voltage rating of 550 V AC. Thanks to its high rupturing capacity, if a short circuit occurs, it will stand up to the high pressure involved.

Part of the RS PRO series, this British standard fuse has been thoroughly tested by leading engineers. It's suitable for use in many domestic appliances and it's compliant with BS 88 and IEC 60269 specifications for British standard fuses.
