The Schneider Electric VW3A7731 is a braking resistor designed for use with variable frequency drives (VFDs) in industrial automation systems. This component is integral to dissipating excess energy generated during motor deceleration, preventing overvoltage conditions within the drive. It is part of the Schneider Electric Altivar series, commonly employed in applications requiring precise motor speed control and energy management.

Technical details

• Product Type: Braking Resistor
• Series: Altivar (VW3A series)
• Resistance: 60 Ohms
• Power Rating: 0.16 kW (160 Watts)
• Enclosure Rating: IP20 (Protected against solid objects greater than 12.5mm, no protection against water)

• Compatibility: Designed for use with compatible Schneider Electric Altivar VFDs. Specific model compatibility should be verified against the drive's technical documentation.

Applications & compatibility

This braking resistor is essential for applications where rapid deceleration of AC motors is required, such as on packaging lines, conveyor systems, and material handling equipment. Its inclusion helps to ensure the stable operation of Altivar VFDs by managing regenerative energy during braking cycles, thereby protecting the drive and connected machinery.
