The Schneider Altivar VW3A4564 is a three-phase line choke rated 613 A with 0.038 mH inductance, sized for harmonic current reduction on Altivar variable speed drives. It is listed as obsolete. Thermal losses run 307 W at full load; voltage drop at rated current is 5%. Overload capability reaches 1.65× nominal for 60 seconds.
Sourcing & Lifecycle Reality
VW3A4564 carries an obsolete lifecycle status.
The 613 A rated current and 0.038 mH inductance target large Altivar drives in the 200+ kW range — this is not a small panel choke. Saturation current is 1150 A, so the core stays linear through transient overloads. The 307 W thermal loss figure means forced ventilation or generous cabinet clearance is non-negotiable; IP00 construction requires the choke to live inside a clean, dry enclosure — not outdoors, not in washdown zones. Operating temperature range is 0…45 °C without derating, with a 2% per °C derating above 45 °C up to 55 °C. Above 1000 m altitude, derate 1% per 100 m. Insulation is Class F; clearance is 5.5 mm, creepage 11.5 mm per IEC 60664 — adequate for 400/480 VAC line-to-line.
Dimensions are 385 mm wide × 440 mm high × 265 mm deep. Bare-wire connection accepts up to 13 mm diameter cable. Vibration resistance is 1 gn at 13…200 Hz, with 1.5 mm peak-to-peak below 13 Hz; shock rating is 15 gn for 11 ms. Mount this choke close to the drive input — long cable runs between choke and drive reduce the harmonic attenuation effectiveness. Environmental classification is 3B1 / 3C2 / 3S1 per IEC 721-3-3, meaning controlled-temperature indoor installation with mild chemical exposure.
Designed to VDE 0160 level 1, EN 50178, and IEC 60076 (with HD398). Pollution degree 2 per EN 50178 — suitable for typical control-room environments, not heavy dust or conductive contamination. Relative humidity range 0…95%, non-condensing. The choke is a passive component; no active electronics, no firmware, no EOL firmware concerns.
