The headline spec the listing carries is a unit weight of 2.80 kgs — enough that one technician can shoulder it onto a DIN backplate, light enough that the panel does not need a reinforced sub-plate to carry it. ## Application read for a VFD specifier For an ACS550 frame, the load profile dictates the parameter set: constant-torque fans and pumps want the heavy-duty current ceiling, variable-torque conveyors and mixers can ride the lighter curve. EMC-wise, mount the drive close to the line entry so the input pigtail stays short — long line-side leads pull common-mode noise past the internal filter stage. On the motor side, keep cable length inside the drive's reflected-wave limit; on a 4 A frame like the -04A1-4 that ceiling is generous, but if a retrofit pushes past it, a dV/dt output filter is cheaper than re-winding a motor after a season of peak voltage spikes at the terminals.","metaTitle":"ABB ACS550-01-04A1-4 Motor Drive, 2.80 kgs","metaDescription":"ABB ACS550-01-04A1-4 from the ACS550 series of motor drives, listed at 2.80 kgs.
