(1) If another current limitation protection device is used, its time-current and thermal constraint (I²t) trip characteristics must be at least equivalent to those of the
recommended protection.
Note: The short-circuit withstand current capability values above have been established for the TN system.
IT system: The short circuit holding current values given above for the TN system are not valid for IT; modications are
required.
