A 50A rated type in a NEMA 12 housing operating at rated current will dissipate 2150W of losses as heat.

By the way, measure the heat loss across a restricted valve. Most of it is carries away in the fluid, but that energy is still lost, and it has to come from somewhere.

So to control the harmonics from a 50 amp motor, the active harmonic filter is losing 2150 watts to heat. Isn't that adding another 2.88 HP load to the system?

IF you have decided that harmonic mitigation is important to you and have decided to use a device such as that, then of the 50A going through it, up to 2150W of that energy will be lost as heat.
BUT (and this is a BIG BUT
