It's a compact wall-mount, so check your panel space: R0 is the smallest in the ACH531 frame range. The 9.4 A normal-use current (In) is your continuous rating at 4 kW; light-overload use (IlD) at 8.9 A gives a bit of headroom for fan or pump duty cycles. Input voltage covers 380-500 V — common global industrial mains, including 400 V and 480 V. IP20 means it's for indoor cabinet installation, not washdown zones.","metaTitle":"ABB 3ABD00049878 ACH531-01 HVAC Drive, 4 kW, 9.4 A, Frame R0","metaDescription":"ABB ACH531-01 HVAC drive, 3ABD00049878, 4 kW normal use, 9.4 A output, 380-500 V, IP20, frame size R0.
