One of the most significant differences between MCCB and ACB is their ratings. The MCCB ratings for current usually range from a few amperes up to 800A, while ACB ratings for can go up to 6,300A. That means an ACB has a much larger current-carrying capacity than an MCCB and, therefore, used in applications Figure 1 below shows an AC current waveform after a fault current situation occurs. Figure 1: AC current waveform behavior after a short circuit fault (Source: Littelfuse, 2007) When selecting the proper fuse, it is important to look at the peak let-through current, I peak (Ampere) and nominal melting, I 2 t (Ampere Squared Seconds), ratings.
