It delivers 5.5 kW in normal use (12.6 A) and 4 kW in heavy-duty use (9.4 A), with an IE2 efficiency rating.
For heavier starts or cyclic loads, the heavy-duty rating of 9.4 A applies — that is the figure to use if the motor is oversized or the duty cycle is demanding. The IE2 efficiency level is standard for this power class; it is not the highest tier but meets most current regulatory baselines. The R1 frame size is compact — expect a wall-mounted footprint that fits in a standard HVAC plant room without special brackets.
