摘要：
This paper presents investigation on electromagnetic repulsion force of contact system for enhancement in repulsion threshold current in MCCB. Current flows on moving contact and fixed contact are repulsive in nature due to structure of contact system. Due to current concentration between electrical contacts and between two conductors, magnetic flux density produces electromagnetic repulsion force. Electromagnetic repulsion force can improve current limiting ability through enhancement in repulsion threshold current of contact system is presented For enhancing in repulsion threshold current of contact system, we calculate electromagnetic repulsion force and finite element analysis are adapted
