Your motor or transformer kicks a startup surge every time you hit the switch, and a regular fast fuse just can't take it. That's what this JAYCAR 500mA M205 slow blow fuse (250VAC) is for. The 'S' or 'T' prefix on the rating tells you it's time-delay — it lets that momentary inrush pass without blowing, then still protects against a sustained fault. Standard M205 cartridge size. $5 RRP. If your panel calls for a T-rated 500mA, this is the one
