The Schneider VW3A5205 is a sinus output filter rated 95 A continuous, designed to sit between an Altivar variable-speed drive and the motor. It converts the PWM waveform into a near-sinusoidal voltage, which reduces motor heating, eliminates reflected-wave stress on long cable runs, and cuts audible noise from the motor laminations. Switching frequency range is 4 to 8 kHz, and the filter is sized for motor cable lengths up to 1000 m at 37 kW or 45 kW on 400 V supplies — a common spec for pumps, fans, and conveyors where the drive must sit remote from the motor. Thermal losses run 250 W at 100 Hz output frequency, so panel ventilation needs to account for that heat. The filter is IP20 — open-frame, intended for a clean indoor enclosure, not washdown or outdoor mounting.
Rated current is 95 A, but the filter can handle 1.5× nominal for 60 seconds — useful for motor starting or short overload events without oversizing. Maximum permissible voltage is 500 V AC, so it works on 400 V class drives with margin. Operating temperature range is -10 to 50 °C, but above 40 °C you must derate current by 1.5 % per °C. Above 1000 m altitude, derate 1 % per 100 m. These derating curves matter if the filter lives in a hot cabinet or a high-elevation plant. Terminals accept up to 50 mm² / AWG 0 conductor with a 6 N·m torque — a solid connection for the 95 A rating. Pollution degree 2 per EN 50178 means it is rated for normal industrial environments with only non-conductive contamination.
Shock rated at 15 gn for 11 ms per IEC 60068-2-27, and vibration rated at 1 gn from 13 to 200 Hz with 1.5 mm peak-to-peak from 3 to 13 Hz — tough enough for most industrial machinery and conveyor applications. Relative humidity tolerance is 0 to 95 % non-condensing, and storage temperature spans -40 to 65 °C. Environmental classification is 3B1, 3C2, 3S1 per IEC 721-3-3, covering stationary indoor use with moderate chemical and mechanical exposure.
