Reliable pull-in at 70%~110%Us, carrying line voltage fluctuation；
The influence of voltage fluctuation:
Considering line voltage fluctuation is an inevitable phenomenon in most application scenarios, short-term pressure loss will cause the contactor to malfunction and affect the operation of the equipment; Frequent pressure loss will cause frequent contactor release, affecting product life and equipment life.
Method to realize：
Matching calculation of suction force and reaction force curve to ensure reliable suction.
