Line choke for harmonic mitigation on Altivar drives
The VW3SKLN110H300 is a 3-phase line choke from the Schneider Altivar range, designed to reduce current harmonics on the input side of variable-speed drives. Rated at 110 A continuous with an inductance of 0.3 mH, it handles overloads up to 1.5 x nominal current for 60 seconds — enough to ride through motor start transients without saturating the core. Thermal losses are 65 W at rated load, so panel ventilation must account for that heat — the IP00 enclosure means it is an open-frame component intended for installation inside a cabinet, not for standalone outdoor use. Compliance with EN 50178 confirms suitability for electronic equipment used in power installations, a standard that covers insulation coordination and clearance for industrial drive applications.
Sourcing and lifecycle — obsolete status
For a BOM line that requires this exact order code, the only channel is the independent surplus and broker market.
Physical fit — dimensions and mounting
The choke measures 315 mm wide, 370 mm high, and 197 mm deep. These dimensions govern the panel layout — verify clearance for the 197 mm depth against the enclosure door or rear wall, particularly if the drive is mounted above or below.
