Description

IEC Standards testing procedures require that the mechanical durability test be carried out without current flowing in the main circuit, with the rated voltage applied to the coil and for at least as many on-off operation cycles as specified for the corresponding intermittent duty class as shown in the table on page 5. The mechanical life of the contactor is inversely proportional to the third or fourth power of the operating voltage. Therefore, if the control circuit voltage is 10% higher than the coil’s rated voltage, the mechanical durability will be reduced by half. An increase in control circuit voltage will harm the operating mechanism, core and shading coil. The results of the mechanical durability test for SC series contactors are given in the table below. The electrical durability test must be carried out for the number of operation cycles specified for the corresponding intermittent duty class shown in the table on page 5, and under the circuit conditions of the corresponding utilization category as defined in the table on page 4. Contact wear is caused by arcing that occurs between contacts when the current is interrupted. The amount of contact wear is directly proportional to approximately the second power of the interrupted current value. Therefore, when a contactor is used for inching or plugging operations, the expected service life of the contacts will be much less than if used for normal operations.
