The 3ABD00048741-D is a wall-mounted ACQ580-01 drive in Frame Size R6, rated for 75 kW normal use (145 A) and 55 kW heavy-duty use (105 A) on three-phase 380-480 V input. It is an active-production unit, IE2 efficiency, IP21 enclosure, NEMA Type1. Intended for water and wastewater applications — the normal-use rating matches the motor nameplate for constant-torque loads like pumps and aerators; the heavy-duty figure governs the overload margin for screw conveyors or sludge presses that need short-term torque above the continuous rating.
The heavy-duty 105 A (IhD) is the 150 % overload capability for 60 s, typical for drives feeding a 55 kW motor in a high-start-torque application. Input voltage range 380-480 V covers most 400 V and 480 V grids worldwide; the 47.5-63 Hz frequency tolerance handles weak mains or generator supply. IP21 means dripproof but not dust-sealed — mount indoors or in a ventilated cabinet. NEMA Type1 enclosure confirms it is suitable for dry indoor locations.
