Do you seriously mean POLYCARBONATE ? They are UNSAFE for across the mains
use
because they have very poor pulse tolerance. It should be a safety X-type

X1 type, large yellow cased , I thought were polycarbonate but I stand
corrected. I thought the critical factor was they had to be self-healing
which could be from pulse or surge.
