Product details

Product and Lifecycle Status

Schneider has classified this part as obsolete.

What the 50 A Rating Means for Fit

The 50 A continuous rating governs the maximum load current the filter can carry without saturating its common-mode choke or exceeding its thermal limit. In a drive application, this means the filter is sized for a drive whose rated input current does not exceed 50 A — typically a 30–37 kW (40–50 hp) three-phase motor on a 400 V supply, depending on the drive's own derating curve. As a three-phase filter, it connects between the mains supply and the drive's line input, attenuating both differential-mode and common-mode noise across the 150 kHz to 30 MHz range typical of EMC standards such as IEC 61800-3. Mounting it close to the drive's line terminals and keeping the input/output cables separated preserves the filter's insertion loss.

Frequently asked questions

Where can I buy VW3A66438 and how do I get a price?

The VW3A66438 is sourced to order against an RFQ through independent distribution channels that handle obsolete and end-of-life industrial automation components. Availability and current pricing are confirmed at quote time — no stock count or price figure is published here because the supply picture changes with each inquiry.

What is the closest pin-compatible alternative to VW3A66438 in this component family?

No official successor order code is listed in the lifecycle record for the VW3A66438. A parametric replacement would need to match the 50 A three-phase rating, the same form factor and mounting footprint, and the same EMC performance class — but without a published cross-reference from Schneider, the buyer should verify mechanical and electrical fit against their specific drive model before substituting.

What is VW3A66438's listed lifecycle_stage (mature) on this component line?

The lifecycle stage is listed as mature, but the official product status is Obsolete. In Schneider's lifecycle nomenclature, 'mature' often precedes the formal end-of-life declaration — in this case the obsolescence has already been enacted.

What is VW3A66438's listed description (THREE PHASES FILTER 50A) on this component line?

The official description is 'THREE PHASES FILTER 50A', indicating a three-phase EMC line filter rated for 50 A continuous current.
