The Manual Motor Starter not required to carry its rated current after the opening and closing cycle. Ics Rated service short-circuit breaking capacity Example 25A 400V required rating 50kA à no backup fuse required until 50kA short circuit withstand 25A 400V required rating 60kA à backup fuse must be 100A AEE-Group_____ April 17 2015 1 Slide 5 nr ABEIGroup April 17 2015 1 Slide 7 AIỈIỈ Motor Protection Rated service short-circuit breaking capacity Ics I I Test of rated service short-circuit breaking capacity The sequence of operations shall be O -1 - CO -1 - CO The rated service short-circuit breaking capacity of a Manual Motor Starter is the current value .
