The text below provides a technical overview and explanation of NEMA MG1-32 and its specific reference to AMP-33 (which typically refers to the Full-Load Current ratings for 3-phase AC motors).
Rule of thumb from MG1-33: If acceleration time exceeds 10 seconds, use a thermal overload relay with memory or a solid-state relay that models the I²t profile. nema mg1-32 amp- 33
