U SERIES FAQ
Selection questions answered from evidence.
Which models are in the U 5.5-11 kW 4P range?
Published data groups 80U45.5, 100U45.5, 80U47.5, 100U47.5 and 100U411 in one 4-pole entry with 80 mm or 100 mm outlets.
Does every model have 50 Hz and 60 Hz catalog records?
No. The current catalog contains nine records. Every model except 100U45.5 has both frequencies; 100U45.5 currently has only a 50 Hz record.
Which motors have built-in protection?
Published data specifically states built-in motor protection for 5.5-7.5 kW. It does not extend that statement to the 11 kW model.
Why is the 100U411 60 Hz voltage flagged?
Published data specifies three-phase 380 V +/-10% at 50 Hz and 60 Hz, while the current 100U411 60 Hz catalog record states 220 V. Written confirmation is required.
Why do the 50 Hz outlet cells show a dash?
All five 50 Hz catalog records leave outlet diameter empty. Published data states 80 mm or 100 mm, but this page preserves raw catalog fields in the configuration table.
