9.3.4 Conductor Cross-sections
1) When connecting cable lugs to DIN 46235 use 3RT19 56-4EA1 terminal cover for conductor cross-sections from
95 mm² to ensure phase spacing.
2) When connecting cable lugs to DIN 46234, the 3RT19 66-4EA1 terminal cover must be used for conductor cross-
sections of 240 mm² and more as well as DIN 46235 for conductor cross-sections of 185 mm² and more to keep
the phase clearance.
