Cheap Manual Reset Breakers

Post by Barboots »

Just wondering if anyone has any experience with these cheap China breakers:

I have a large margin between the circuit capacity and the fuse rating, so precision isn't so important. However they do need to work if required!

I can get the common smaller breakers for about the same money locally with manual reset, but the switch feature appeals. This takes the local cost to $80 odd, which does not appeal [emoji1]

Any feedback appreciated.

Cheers,
Steve

With protection, for me a dollar well spent is many dollars saved. If I was to use these I would want to do some extensive testing to make sure they would perform, and more importantly, at what point, and at what speed. A slow response may well allow what you are trying to stop, happening further down the line.
The Jaycar ones are similar, 100 amp at $27, you can bet they have been tested to be sure they will work.
Having said that my very extensive protection system is all Bussman, bit more expensive but they do what they are installed to do with no maybes.
Old saying, you get what you pay for may apply here.

Some work ok, had one that didn't conduct any power at all out of the box and disassembly meant destruction.
I "tested" a few before installation and they tripped but no idea at what current level as didn't have the gear to measure it.
Looking at the locally available ones and the Chinese sourced ones they seem to be identical.
I wouldn't use them for anything critical, better to use maxi fuses.
