The Schneider Electric VW3A7735 is a braking resistor designed for use with variable frequency drives (VFDs) to dissipate excess energy generated during motor deceleration. This component is part of the Schneider Electric Altivar series, commonly integrated into motor control systems requiring dynamic braking capabilities to manage regenerative energy and prevent overvoltage conditions. The resistor's specifications are critical for ensuring proper VFD operation and system safety.

Technical details

• Product Type: Braking Resistor
• Resistance Value: 8 Ohms
• Power Rating: 1.1 kW (kilowatts)
• Enclosure Rating: IP20 (Ingress Protection rating indicating protection against solid objects greater than 12.5mm and no protection against water)
• Series Compatibility: Designed for use with Schneider Electric Altivar variable frequency drives. Specific model compatibility should be verified against the drive's technical documentation.
• Functionality: Dissipates regenerative energy generated by a motor during deceleration, preventing overvoltage within the VFD DC bus.
• Construction: Typically features a robust construction suitable for industrial environments.

Applications & compatibility

This braking resistor is essential for applications where rapid deceleration or frequent stopping of motor loads is required, such as in packaging machinery, material handling systems, and machine tools. It ensures the stable operation of Altivar VFDs by managing the energy feedback from decelerating motors, thereby protecting the drive and connected equipment from potential damage due to voltage spikes.
