The VW3A66702 is an enclosed braking resistor from the Schneider Altivar 66 range, rated at 28 Ohm and 200 W average power. It is designed to dissipate regenerative energy from the DC bus of an Altivar 66 drive during deceleration — a common requirement for high-inertia loads like centrifuges, conveyors, or fans. The IP30 enclosure keeps hands and tools out but is not sealed against washdown; mount it inside a panel or cabinet where ambient dust is limited.
Schneider lists the VW3A66702 as obsolete. No official successor order code is provided in the record.
