초록
The higher the short circuit currents, the faster the interruption takes place. For increasing the interrupting performance of the MCCB, it is important to design optimally the adjustable tripping device, the open /shut mechanism, and the arc quenching room in the MCCB. This paper is focused on understanding the interrupting performance, more specifically of the grid and the fix contact, based on the shape of the arc quenching room in the current MCCB.
