What is the capacity of whirlpool freezer AFB 823/3

This one requires more information. If the breaker trips randomly, then I say there is grounding problem between the plug and the freezer itself. I know the UK has a very large plug and it requires a serious connection into the wall. I would check and make sure you have a good ground on the box itself. You may have to removed the back and look at the connections If you have a V-OHM meter you can verify the ground through different parts of the freezer. If this never happen before and you just bought this freezer I would replace the breaker with a new one. The breaker maybe damaged and sensitive to heat from the current draw of the freezer. Also make sure it is the correct ampere required to run the freezer.
