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-
ing voltage. Category II is for electrical equipment.
Pollution degree indicates the degree of existence of solid, liquid, gas or other
inclusions which may reduce breakdown voltage. Degree 2 is the normal indoor
environment.
