The ABB 3ABD00045414-D is an LV AC wall-mounted drive for HVAC, rated 55 kW normal-use output at 106 A on a 380–480 V three-phase supply. Heavy-duty use drops to 45 kW at 87 A; light-overload use holds 55 kW at 100 A. Frame size R5, IP21 enclosure, IE2 efficiency.
Normal-use (Pn 55 kW, In 106 A) covers constant-torque HVAC fans and pumps at full speed. Heavy-duty (PhD 45 kW, IhD 87 A) handles variable-torque loads like compressors or conveyors where peak current is higher. Light-overload (PlD 55 kW, IlD 100 A) suits cyclic loads with moderate overloads. Match your motor's full-load amps to the appropriate column — oversizing to normal-use when the load is actually heavy-duty risks nuisance tripping.
Wall-mounted, IP21, NEMA Type 1 — suitable for indoor, non-condensing environments. Frame R5 means a specific footprint and gland-plate layout; verify panel cut-out dimensions against the installation manual before committing the backplate.
