Mini Circuit Breaker Ratings
Mini Circuit Breaker Ratings
(OP)
Hello everyone,
We have designed a Lamps testing board with 4 holders. Firstly, we used fuse of 3 Amps in it as a protection device. We would like to replace the fuse with circuit breaker as it blows up every other day.
The load on this testing board will vary from 5W to 300W depending on the lamp we use. What rating of (mini) circuit breaker would be suitable for this purpose?
Regards,
E

If you want to protect each of the different sized lamps when plugged in to the board, you will then need separate breakers for each size and some sort of selector switch to make sure you have the right one in the circuit. In that case, determining the exact nature of each individual lamp load would be more critical. Might be easier to use some sort of programmable electronic current sensing relay for that though, and just rely upon the breakers to cover any maximum load and/or short circuit scenario, in which case you would go back to the first method I mentioned.
