The Schneider Electric VW3A7818 is a braking resistor designed for use with variable frequency drives (VFDs) in demanding industrial environments. This component is part of the Schneider Electric Altivar series, commonly integrated into motor control systems requiring dynamic braking capabilities to dissipate excess energy during deceleration.

Technical details

• Series: Altivar
• Resistance: 5 Ohm
• Power Rating: 70 kW
• Enclosure Protection: IP23
• Function: Dynamic Braking Resistor
• Application: Energy dissipation during VFD deceleration
• Compatibility: Designed for use with compatible Schneider Electric Altivar VFDs. Verify specific model compatibility with the manufacturer's datasheet.

Applications & compatibility

This braking resistor is essential for applications where rapid deceleration of motor loads is required, such as in material handling systems, elevator drives, and high-inertia machinery. Its integration helps prevent overvoltage conditions within the VFD during braking cycles, ensuring system stability and protecting drive components.
