The Schneider Altivar VW3SKLN070H550 is a 3-phase line choke (line reactor) rated for 70 A continuous current with 0.55 mH inductance, designed to reduce current harmonics on the input side of a variable frequency drive. It carries a 50 W thermal loss figure and is built to EN 50178 for electronic equipment in power installations. The IP00 rating means it is an open-frame component intended for enclosure mounting — no splash or dust protection built in, so panel placement matters.
Sourcing reality — obsolete, but available
Schneider has marked the VW3SKLN070H550 as Obsolete.
The 70 A rated current is the continuous RMS value the choke is designed to carry without exceeding its thermal rise. The 0.55 mH inductance sets the impedance at line frequency.
Physical integration
The envelope is 300 mm wide, 410 mm tall, and 180 mm deep. That is a substantial block — plan for a backplate or chassis-mount inside the panel, not DIN-rail snap-on. The IP00 construction means all terminals and windings are exposed; maintain at least the standard creepage and clearance distances per EN 50178 to adjacent metalwork and live parts.
