a) Performance factor

= describes the relationship of effective power to apparent power
b) Protection class = Extent of protection offered by housing against penetration of solid foreign matter and
water (IP23 = protection against solid foreign matter > 12.5 mm

and against splash
water)
c) Insulation class = Class of the insulation materials used and their highest permitted constant
temperature (B = highest permitted constant temperature 130°)
d) Short-circuit
performance, main
supply
S
S C
= minimum permitted short-circuit performance of the main supply system in
