Will standard mcbs work on 12v AC?

hertzal123
The customer is using a 300va 12v tx to supply 5 no 60w takeaway heated food bags

and is having problems with the 5 no 10A ceramic fuse holders overheating on their spade terminals.

I wondered if B10 mcb,s would solve the problem,or would they be too slow to protect the tx on a short

cct on one output?

                         Regards,

    The manufacturer is permitted to assign the voltage(s) an mcb will operate at, and associated rated short-circuit capacity.


    According to BS EN 60898-1, there is no obligation on the manufacturer to guarantee operation at lower voltages than 230 V (nominal).


    So ... check with the manufacturer's data.
