The VW3A7286: The unit delivers 770 V DC from a 480 V AC three-phase supply, and can handle overloads of 1.20× nominal current for 60 seconds or 1.35× for 2 seconds. That transient capability matters when sizing the DC bus for motor deceleration events — the converter absorbs the regenerated energy rather than dumping it across a brake resistor.
Physical footprint and panel integration
This is a built-in unit (not an enclosed drive) measuring 1100 mm wide by 1150 mm high by 377 mm deep. The IP00 rating means it requires enclosure protection — the panel builder must provide the ingress barrier and coordinate the 2000 cm² air flow surface with the 2400 m³/h forced-convection cooling for the power circuit plus 660 m³/h for the control circuit.
Sourcing reality — obsolete, sourced through independent channels
Schneider Electric lists the VW3A7286 as obsolete. For a line-down situation or a BOM that requires this exact active infeed converter, the only channel is independent surplus and broker stock. Availability is lot-specific and confirmed at RFQ — there is no standing inventory to draw from. The unit carries EN/IEC 61800-5-1 certification for adjustable-speed drive systems, pollution degree 2, and environmental ratings 3K3/3C2/3S2 per IEC 60721-3-3. These standards matter for the compliance file: if the original installation was certified under these norms, a replacement unit must match them to avoid re-certification costs.
