KSB 1AV3112A 1PC30381BA234GP1UD Three-Phase Motor
1. Product Overview
1AV3112A 1PC30381BA234GP1UD is a KSB low-voltage three-phase asynchronous motor used to drive its pump sets. Motor type 1AV3112A is built on the Simotics GP general-purpose platform (squirrel-cage rotor, fan-cooled). It has an aluminum enclosure, IE3 premium efficiency, 2 poles, IEC 112M frame, rated 4 kW (50 Hz) / 4.55 kW (60 Hz), about 2900 r/min at 50 Hz, IP55.
The order/config number 1PC30381BA234GP1UD specifies mounting, voltage, lead orientation and options; this motor typically drives KSB centrifugal pumps (e.g., Etanorm). Exact mounting (B3/B5/B35), voltage and options should be confirmed from the nameplate.
