I wondered if anyone could recommend a replacement for this part, its a motor thermal overload protector from a 4hp pump.

The writing on it says the following

8AM4
BLFA11
T8R

Googling suggests it is made by Sensata, but I am struggling to order one in the UK.

Can anyone recommend a replacement part that would be easy to source?

Pictures attached

Do you know the cutoff temperature? could look at something like these if original parts aren't a requirement: https://www.ebay.co.uk/itm/KSD-9700-Temperature-Sw...

RS components usually have stuff like this and you can find parts. If its melted then thermal overloads generally let go when there is already some insulation damage from heat on the motor windings, are you sure the pump is still ok? Insulation resistance check and continuity advised if so.
