Abstract

Through the Standard of UL489, the Adjustable Type Instant Trip Unit should NO trip at 80% of each current from $5{\times}In$ to $10{\times}In$ and trip 130% of those. In this paper, we obtain the attraction force between Fixing Magnet and Moving Armature. we simulated the modelling by 3D Finite Element Method. With values of experiment and simulated values, in this paper, we show the method for set up the process of designing Instant spring.
