WebAug 26, 2024 · When choosing MCB curve types for high-current circuits one of the most important factors to consider is the tripping time and tolerance to inrush current. This is because the inrush current can cause tripping in some MCBs and not others. WebThere are four factors you need to take into account when choosing an MCB: 1) Current rating. This is the rated current on which the tripping characteristics will be based. 2) Tripping characteristics. The multiple of the current rating at which you want the MCB to trip. This will determine the MCB Type. 3) Breaking capacity.
