The 3ABD00045436-D: Normal-use output (Pn 55 kW, In 106 A) is the spec to size against for constant-torque loads like pumps and fans. Heavy-duty (PhD 45 kW, IhD 87 A) covers demanding applications such as conveyors or crushers where peak current is sustained. Light-overload (PlD 55 kW, IlD 100 A) sits between — same power as normal but slightly lower current, useful when the duty cycle is intermittent. Matching the right duty class to your load avoids oversizing or nuisance trips.
Wall-mounted, IP21, NEMA Type 1. Frame size R5.
