It's rated for a continuous 1600 A at 440 V AC, 60 Hz, with an inductance of 17 µH and a 4% relative inductive voltage drop at rated current. That 4% drop is typical for a drive input reactor — enough to smooth line notches and limit harmonic current without dragging the DC bus voltage down too far under load. Coil loss 780 W, iron core loss 400 W. IP00 open-frame assembly requires cabinet with forced airflow. The flat-type terminals on the main circuit are sized for bus-bar or heavy cable lugs — this is not a wire-in terminal block. Mature lifecycle status from Siemens. Available through independent distribution; sourced and quoted to order. Footprint is 0.46 m wide by 0.435 m tall, with a depth of 0.293 m. That's a substantial chunk of iron — plan for a dedicated mounting plate or floor-standing cabinet section. The flat-type terminals need bus-bar takeoffs; factor in bending radius and clearance for the lugs. At 1600 A continuous, the bus-bar cross-section and connection torque must follow the manufacturer's guidelines. The IP00 rating means no integral enclosure — the installer provides the cabinet and its ventilation. Forced air is strongly recommended given the 1180 W total loss.","metaTitle":"Siemens 4EU4551-0AE10-0B Mains Choke for VFD, 1600 A, 440 V","metaDescription":"Siemens 4EU4551-0AE10-0B mains choke for variable frequency drives.
