Drive-side harmonic filter, sized for one ATV610
The VW3A46104A is a passive filter dedicated to a single Schneider Altivar 610 variable speed drive powering an 11 kW / 15 hp motor. It mounts between the line supply and the drive input, rated for 380…480 V three-phase at 50 Hz. It delivers a 10 % THDI on the line side — meaning input current distortion drops to that level under rated load. That figure matters for installations with weak mains or multiple drives on the same bus, where cumulative harmonic content can trip upstream protection or overheat distribution transformers. Efficiency sits at 98 % with 203 W of thermal losses at full current, so the heat it dumps into the enclosure is modest for a filter in this power class. The IP20 enclosure mounting means it needs cabinet space with clearance for natural convection — no fan required, but don't bury it against the gland plate.
Termination and wiring constraints
Line and load connections use, L2, L3 and ', L2', L3' terminals accepting 0.5…10 mm² conductors. The DC-bus choke terminals (D1, D2, D3, D1', D2', D3') are fixed at 2.5 mm²; the thermal-switch terminals (TS, TS') accept 0.5…4 mm². Strip lengths and torque values follow the standard Schneider terminal marking on the filter body. The input current rating is 16.2 A, output side is 25.1 A — the filter is sized for the drive's full-load motor current, not the lower line draw. That 25.1 A output rating is the number to match against the ATV610's rated output current for the 11 kW frame.
