For Example:-

Onics

HPAR 1.5kw 100R K T W3 MM/YY

Onics – Brand Name

hpar1.5kw – model number

100R = Resistance Value,

K=tolerance 10%,T=thermal switch,W3=wire terminal300mm Length, MM/YY = Month/Year of Manufacturing

Note: -

For 5% tolerance use J instead of K.
For 500mm wire terminal length use W5 instead of W3.
For clip terminal use C instead of W3 or W5.
