Abstract:

This article verifies and analyzes the factors that affect the pull-in time of AC contactor,mainly including contact bounce,coil parameters,and electrical pure iron grades.By optimizing the contact spring parameters,strictly controlling the force of the contactor contact spring,optimizing and adjusting product coil parameters,and using high-grade electrical pure iron,etc.,it can effectively reduce the pull-in time of the AC contactor and make the suction characteristics of the product better.

Key words: AC contactor, pull-in time, affecting factor, coil parameter
