The electrical life of the Schneider ICT63A contactor is clearly differentiated by load type. Although the mechanical life is not separately specified, it can be confirmed with reference to the parameters of its same-series products and industry standard designs. The specific information is as follows:
- Electrical Life
This parameter varies with load categories, mainly because the on-off current and voltage characteristics of different loads cause significant differences in contact wear of the contactor. The specific values are:
– For AC-7a or AC-1 loads such as lighting, the electrical life can reach 100,000 operations.
– For AC-7b, AC-3 loads such as motors, and other common load types including AC-7c, AC-5a, and AC-5b, the electrical life is 30,000 operations.
- Mechanical Life
Schneider does not separately specify the mechanical life value of the ICT63A. However, the mechanical life of such modular contactors is usually much longer than their electrical life. Additionally, based on the general design logic of Acti9 series contactors and the characteristics of similar products, their mechanical life can generally reach millions of operating cycles.
Mechanical life mainly depends on the wear of internal components such as springs and transmission mechanisms, and applies to on-off operation cycle scenarios under no-load conditions.
