4A M205 Quick Blow Fuse 250VAC – Fast-Action Cartridge Fuse for Overload Protection

Device won't power on and the fuse holder's got a charred little cylinder in it? If the rating stamped on that old one reads 4A, this is your replacement. The 4A M205 quick-blow cartridge fuse (250VAC) is built to open circuit fast — before an overload or short can damage the board behind it. It's the same M205 size used across a huge range of gear, so if your manual or parts list says 4A fast-blew at 250VAC, this drops straight in and you're running again

• 4A fast-action (quick blow) rating for instant open-circuit on overload or short
• M205 cartridge format — a drop-in fit for a wide range of devices and appliances
• Rated 250VAC for standard Australian mains circuits
• Sometimes marked F4A on the body to confirm fast-blew type
