Heavy-duty (PhD 350 kW, IhD 360 A) applies when the drive must deliver rated torque down to zero speed — think a winder or a vertical load that needs holding torque. Light-overload (PlD 450 kW, IlD 420 A) is for variable-torque applications like pumps and fans. If your line-down spare is for a machine that cycles between high-torque and idle, the heavy-duty figure governs the thermal limit.
The 3ABD00059280-D carries an active lifecycle status. No PCN or end-of-life notice is on record, so it remains a standard catalog line for new builds and spares.
Frame size R10. Module mounting, IP20 enclosure, NEMA open type. The 525-690 V input range means it lands on a 690 V distribution bus without a step-down transformer. Three-phase input, 48-63 Hz compatible.
