(1) For installation with a class 30 relay, a derating of 20 % must be apply on circuit breakers.
(2) Valid for 480 V NEMA.
(3) Reversers: replace LC1 by LC2.
Note: where more than one association is possible for a rated power, if the motor starting current is high or unknown, the highest association shoud be applied.
