For selection of the suitable contactor-type according to supply volt­age, 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

M = Contact life (switching cycles) for AC3/AC4-mixed operations

C3 = Contact life (switching cycles) for AC3 operations (normal switching

conditions). Breaking current I

C4 = Contact life (switching cycles) for AC4 operations (inching).

Breaking current Ia= multiples of rated motor current In.
