IMO it's almost certainly polypropylene (MKP), not polyester (MKT). Pretty-well all AC-rated caps for motor start/run and power-factor correction are polypropylene these days.

And how do you work that out, oh wise one?

Stuartsblog submitted this idea :
I c14uF and rated 400v AC for temperature band A, with a tolerance of + or
- 5%. 13uF or 15uF would be fine.
No need for 500VAC. Its 500VDC to cope with 415V peak to peak voltage of a 230v AC RMS supply.
Actually its more like 275V AC..
NO. 400V DC is the rating, or around 250V AC. Most motot start caps are quoted as AC rated..
Is this in the same sense as "night soil" as a euphemism?
cheers, Pete.
