The Schneider Altivar VW3A4562 is a three-phase line choke rated 429 A continuous with 0.049 mH inductance, designed to reduce current harmonics on variable-speed drive inputs. It handles 1.65× nominal current for 60 seconds — enough to ride through a motor start or a short overload without saturating the core.
This part is obsolete per the manufacturer. No official successor is listed.
Mounts as a line-side choke between the mains and the drive input. IP00 enclosure means it's intended for a cabinet — no washdown rating, no outdoor exposure. Bare-wire connection accepts up to 13 mm diameter cable. Thermal losses of 278 W need to be factored into the panel's cooling budget.
Rated for 50/60 Hz supply. Voltage drop at rated load is 5%. Insulation is Class F. Pollution degree 2 per EN 50178, with 11.5 mm creepage and 5.5 mm clearance distances conforming to IEC 60664. Ambient operation is 0–45 °C without derating; above that, derate 2% per °C up to 55 °C. Altitude derating applies above 1000 m.
