Specification Verification Note:

Some distributor listings provide 400–480 VAC input, 10–16 A output, 7.5–11 kW motor power, IP20 protection and STO functionality for this model. These values have not been independently verified against an exact-model manufacturer rating table and are therefore excluded from the confirmed specifications.
