Since April 2006, the short-circuit resistance (SCCR) requirement has been specified on a power plate for industrial controllers, which are combined for all main circuits and for the supply of the control voltage supply.   The SCCR values can be determined using UL 508A. Default values for unspecified equipment are listed in Table SB 4.1 in UL 508A. WAGO rail-mount terminal blocks with a value of 10 kA are listed in this table.    For the individual WAGO rail-mount terminal block system(s), a higher SCCR value (100 kA) has also been documented for the fuse types/designs J, T, RK1, G and CC (see appendix).   In conjunction with different circuit breakers, the SCCR value must also be assumed to be 10 kA.   More details can also be found in UL File E45172.
