Motor ratings are guide values for 4-pole standard motors at 50 Hz 400 V AC; the actual starting and rated data of the motor must be considered. Versions for special conditions down to −50 °C have limited mechanical endurance and no UL/CSA, ATEX or IECEx approval (catalog footnote). Auxiliary switches and other accessories are ordered separately.
