Schneider Electric · VFD Accessory
VW3A8306R is a Schneider Electric industrial component with Rated operational voltage 3-phase 400 V AC; Supply voltage 200...240 V or 380...500 V; Enclosure rating IP20 (when mounted in enclosure). It is used in control panels, machine builds, spare-part replacements where the installed unit is matched to the original catalog number and a compact, documented part is required.

All variants share the same VFD Accessory footprint and terminal layout; the columns above show where they differ. Selecting a different catalog number changes the electrical interface, not the mounting.
Where it sits in the control system
The VW3A8306R is the device-level element in a Schneider Electric industrial component installation. It receives the field signals and control supply listed above — 200...240 V or 380...500 V — and switches or conditions the load within the 3-phase 400 V AC ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides Cabinet / panel mount support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Before you specify
-
Ratings. Confirm the rated current and voltage match the circuit before specifying; sizing from the nameplate avoids field mismatch.
-
Mounting. Check the Cabinet / panel mount fit against the existing enclosure before ordering.
-
Marking. Record the catalog number and revision from the nameplate of the installed unit for a like-for-like spare.
Technical FAQ
Q.What supply does this device require?
It requires 200...240 V or 380...500 V. Size the supply source to the same rating shown in the Specifications table.
Q.What are the key electrical ratings?
The confirmed ratings include 3-phase 400 V AC and CE, UL, CSA marking. Cross-check them against the installed unit's nameplate.
Q.How is this device mounted?
It mounts by Cabinet / panel mount. Confirm the cutout or rail before ordering a like-for-like spare.
Q.What replaces a unit that is no longer in production?
For a like-for-like spare, record the catalog number and revision from the nameplate; a current-production equivalent is identified by matching function and ratings.
