Active infeed converter for high-power drive lines
The VW3A7258 is a 675 kW active infeed converter (AIC) from Schneider Electric, designed for 380-480 V AC three-phase supplies. It delivers 1023 A continuous output current at both 400 V and 480 V, with overload capability of 1.20× nominal for 60 s or 1.35× for 2 s. This unit is part of an Active Front End system — it handles low harmonics and energy regeneration, making it a fit for applications where power quality or braking energy recovery matters.
Physical footprint and installation constraints
The built-in unit measures 1110 mm wide by 1150 mm high by 377 mm deep. IP00 means it is an open-frame assembly — it needs to be installed inside an enclosure that provides the required environmental protection and touch safety. Forced convection cooling moves 2400 m³/h for the power circuit and 660 m³/h for the control circuit. The enclosure must allow at least 2000 cm² of free air flow surface to keep thermal losses (11060 W) within limits.
Lifecycle status and sourcing
Schneider Electric lists the VW3A7258 as obsolete. No official successor or pin-compatible alternative is recorded in the product documentation. Sourcing is through independent distribution channels — quantities are confirmed at RFQ, and current pricing is quoted against the BOM line.
