Jaycar 7.5A Manual Reset Standard Blade Circuit Breaker – 28VDC, SF2331

You've got a motor or relay on a low-voltage circuit that needs a bit more headroom than a 5A fuse gives you, but you don't want to jump straight to 10A and lose protection. This 7.5A blade breaker sits right in the middle. Current spikes past 7.5 amps on a circuit up to 28VDC and the button pops out. Clear the fault, push it back in, back online in seconds. Fits the same standard blade slots as your existing fuse blocks or panels — body is 24 × 20 × 6 mm (add 1 mm for the reset button), 32 mm total with blades. Swap it in, wire it up, and stop worrying about that one circuit that keeps blowing its fuse. Add to cart
