Overview of the approved protective devices according to UL standards • JDDZ: Fuses of any manufacturer. • DIVQ: Siemens circuit breaker • NKJH: SIEMENS Type E combination motor controllers ICC conditional short circuit current Icc: The maximum RMS value of a prospective short circuit current, available from a supply source. Short-Circuit Current Rating (SCCR): The Short-Circuit Current Rating (SCCR) is the prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected without sustaining damage exceeding defined
