About these values
Calculated from EMPD tested 50 Hz / 400 V data (output × 1.15, speed × 1.2) and confirmed by test on order with a 60 Hz test certificate. SF 1.25 proven by heat run at type test; report supplied at first-article approval. Continuous-duty (S1) motors sold in the US must meet NEMA Premium efficiency and be DOE-certified. Please contact EMPD to discuss.
Frames are IEC metric; NEMA frames 56C to 256T built to MG 1 on request. Please confirm certification requirements (e.g. UL / CSA) at enquiry.
