Questions & Answers

Q:This would be correct for a 208v 3 phase 5 hp. Motor?
by|Apr 2, 2021
1 Answer
Answer This Question

A:  At this time we do not have ratings at 208V for GNF321RA. The 240V rating would cover operation at 208V. The LRA current used in testing the 30A 240V at UL is 92A, so as long as the LRA of the 208V motor doesn’t exceed 92A then it is permissible.
