I need a new breaker for my 24 Volt electric lawnmower. The part is almost the same part shown in the third picture here. Where that says “24V P40 40A”, mine says “24V N49 40A”. I have no idea if the N49 vs P40 is significant, or just a manufacturing lot number or date code.
There’s a similar part here, 24 Volts, and I can select 40 Amps. Is that probably OK, or is there some other factor that might trip me up? There’s another one here for triple the price, with “S15” instead of “N49”.
Extra bonus points if you can find one at Grainger.com. There’s a brick and mortar Grainger near work that I could stop at to pick it up if they have it in stock, but I haven’t seen anything that looked like that part when I’ve searched there. Maybe I just don’t know the correct term to use, though.
Take the part in to your local Grainger store and ask them to find it for you. I have found them to be very helpful.
The N49 vs P40 I do not know, but it may have to do with wheather the switch is a N.O. (Normaly Open) or a N.C. (normaly Closed) type of switch. It may also denote which way a spring inside of it pulls.
With the voltage and current specified, there’s only specs on the packaging and connectors.
There is no code which includes P,N,S … I guess its just a internal use design number…
Thanks. Searching by the manufacturer, I was eventually able to track down similar parts at Grainger.com. They only seem to have 14 volt ones, though, and I need 24 Volt. I’ll stop by there anyway on the way home tonight and see if they have more than shown online.
Otherwise, the one in the link in MY OP looks like the best match. It’s Type I instead of Type II (gold case instead of silver), but that just means it will reset without the power being disconnected first. I think that will be OK.
Thinking about it, I decided that N49, P40, S15 probably are just lot numbers, with the letter changing every year.
