The VW3A68710 is an enclosed braking resistor from Schneider Electric, rated at 4.5 Ohm and 26 kW, with an IP23 enclosure. It is designed for use with Altivar variable-speed drives to dissipate regenerative energy from decelerating motor loads — typically on conveyors, centrifuges, or hoists where the load overhauls the motor.
Deployment context
The enclosed form factor (IP23) is intended for panel-side or machine-frame mounting, not inside a sealed cabinet. It requires free air circulation around the enclosure for convective cooling. The resistor generates significant heat during braking — plan for at least 100 mm clearance on all sides and avoid mounting near temperature-sensitive components or wiring.
