Protection Each molded case switch must be protected on the supply side by a coordinated device which safe- guards it against short-circuits. The section "Coordination" in the table below shows the correspondence between each molded case switch and the relevant circuit-breaker.
Making capacity The making capacity Icm is highly important since a molded case switch must be able to withstand the dynamic, thermal and current stresses which can occur during closing operations without being de- stroyed, right up to short-circuit closing conditions.
