Category based on IEC 1010: II (Note)
Pollution degree based on IEC 1010:2 (Note)
Note: Installation category, called over-voltage category, specifies impulse withstand
voltage. Category II is for electrical equipment.
Pollution degree indicates the degree of existence of solid, liquid, gas or other
inclusions which may reduce dielectric strength. Degree 2 is the normal indoor
environment.
