Position 5 – Motor insulation class

C – Class 200; S – Class 200 with jacket;

Note  – Standard 100 boundary is class H.  table 4 & 10 of CSA 100.  If you reach 195C & insulation is good for 200, motors cannot get hotter.  Limit of the motor temp will be 180C.

Insulation classes will be assessed to class H as per maximum in the standards.  Our report will spell out all insulations used, but our assessment will use the limits of class H.

Position 6 – Nominal supply voltage

1. 2 – 180~260V;
2. 4 – 300~480V;
3. 6 – 500~690V;
