Why are there no heavy duty 25 amp breakers?

[Mikedefieslife]

I'm looking for a 25 amp breaker that's going to give me minimal voltage loss.

Ideally something like this:



Unfortunately bar the Bussmann 25X which isn't available anywhere, they don't seem to exist anywhere in Europe.

My other option is to use a 25 amp fuse, and a switch. Yet all the fuse holders I've seen use tiny 4mm wire maximum, and the switches induce a large voltage drop.

I'm running 16mm2 cable and powering a DC motor. The mega fuse holders are the only decent ones I've seen, but mega fuse start at 50 amps.

You might consider Midi Fuses rather than Mega Fuses. Smallest is 30A, and the holder takes 16mm2 cable.

What about this one:

I'm selling on ebay only £7 plus P&P. OK you can have it for £9 all in !

Ah yes midi fuses, i forgot about those. The manufacturer calls for a 25amp fuse, though the motor itself is is 250w. When on it runs continuously for hours at time and draws between 15-18 amps.

That's more the type for a breaker board. I can't mount that on a bulkhead type surface.

If you can put up with buying from the USA, this might be what you're loooking for

The fuse is to protect the cable; a 30A Midi Fuse would be fine.

Something like this ? ; http://www.rjsmarine.co.uk/7180-285-series-circuit-breaker-surface-mount-25a

Bluesea 25A (£85 from Amazon)?

Bog standard 30A (£25 from Amazon)?

I have two of the 150A versions of the latter protecting my house and engine circuits.

Cool, cheers, guys. I'll go with a panel mount 30a breaker.
