Contact Life
For selection of the suitable contactor-type according to supply volt-
age, power rating and application (utilization category AC1, AC3 or
AC4) use contact life characteristic diagram.
For the most common supply voltages four scales of power ratings P
are provided for each utilization category.
Select contactor-type according to utilization category AC3 (breaking

For contactors frequently used under AC3/AC4-mixed service condi-
tions calculate contact life with the formula:
M = Contact life (switching cycles) for AC3/AC4-mixed operations
AC3 = Contact life (switching cycles) for AC3 operations (normal switching
conditions). Breaking current I
AC4 = Contact life (switching cycles) for AC4 operations (inching).
Breaking current I
%AC4 = Percents of AC4-operations related to the total cycles.
