Default 10A DIN circuit breaker

I'm trying to provide some better over-load/over-pressure protection for the Sanyo.
Adding a (Used Ebay) 10A motor protector type breaker. It's a DIN, which will require a new box.



It's installed temporarily on the outside of the box on the left side.
It's wired in series with the old 15A breaker-pair..

Unfortunately, as I was wiring it in, I noticed a problem. Some hacker
has been tweaking the Amp settings. I could tell, because he broke
part of the head off one of the adjustment screws.
A replacement is on the way now.

Anyways, my theory is a 2.5kW breaker (250v X 10A = 2500 watts)
that trips at 125% is way better than a 15A breaker. (3750W).
Since max input during heating, should be 2490 watts. (Sanyo Spec).

I'll bet that 15A breaker would trip, up around 20A. Or 5kW

So far, the hacked breaker hasn't popped. So, my guess is, it's set real high.
I can picture the service guy in the field. He has a motor that's going bad.
It's drawing over 10A. He is too tired or dumb to replace the motor,
so he adjusts the breaker to max current. (29 amps?)
End of problem. He figures any evidence will be destroyed in the ensuing fire.

The replacement DIN 10A breaker came today. It looks brand new.
It's installed and seems didn't pop at 1500w, so it might be okay..
