The 73 A normal-use current (In) is the continuous output the drive can deliver at rated conditions — size the input feeder and motor cable for this figure. Light-overload use is rated at 68 A (IlD), which gives a small headroom margin for occasional peak demand without upsizing the drive frame. Rated for HVAC variable-torque applications — fans, pumps, compressors in commercial buildings and light industrial ventilation. The IE2 efficiency level meets current minimum efficiency standards for most markets, though some regions now require IE3 or IE4 for new installations; check local energy regulations if this is a new design rather than a like-for-like replacement.","metaTitle":"ABB 3ABD00046935-D ACH531-01 HVAC Drive, 37 kW, 73 A","metaDescription":"ABB ACH531-01-073A-4+X1663 wall-mounted LV AC drive, 37 kW, 73 A, IP20, IE2.
