General
Utilization categories determine the current making and breaking conditions relating to the characteristics of the loads to be controlled by the contactors. Interna-
tional standard IEC 60947-4-1 and European standard EN 60947-4-1 are the standards to be referred to.

• Category AC-2: I
• Category AC-4: I
Generally speaking I
On pages 1.66 - 1.71, the curves corresponding to categories AC-1, AC-2, AC-3 and AC-4 represent the electrical durability variation of standard contactors in
relation to the breaking current I
Electrical durability is expressed in millions of operating cycles.
These curves have been plotted for 400 V - 50 Hz 3-phase currents but remain valid up to 690 V - 40 ... 60 Hz provided that a check is carried out to make sure

• Note the characteristics of the load to be controlled:
• Defi ne the number of operating cycles N required.
• On the diagram corresponding to the operational category, select the contactor with the curve immediately above the intersection point (I

• Note the characteristics of the motor to be controlled:
• Defi ne the total number of operating cycles N required.
• Note the smallest contactor rating compatible for AC-3 (U
• For the selected contactor make a note of the following in relation to the voltage using diagram AC-3 page 2/85 and AC-4 page 2/86 or 2/87:
• Calculate the estimated number of cycles N' (N' is always below A)
Case of uninterrupted duty.
Among the different utilization categories, the uninterrupted duty implies the following remark. The combinated effect of environmental conditions and the proper
temperature of the product may require some disposals. As a matter of fact, for this duty, the use duration prevails over the number of operating cycles.
For long term service, some verifi cations of preventing maintenance are needed to check the functionality of the concerned product (consult us).
Over a duration of fi ve years, in these conditions the contactor might present high internal resistance. We recommend to change the contactor or change the
contacts.
