The Schneider Electric VW3A7703 is a braking resistor designed for use with variable frequency drives (VFDs) to dissipate excess energy during deceleration. This component is part of the Schneider Electric Altivar series, commonly integrated into motor control systems for applications requiring controlled stopping and energy management. Its robust construction ensures reliable performance in demanding industrial environments.

Technical details

• Product Type: Braking Resistor
• Manufacturer Series: Altivar (implied by part number prefix and common usage)
• Resistance: 28 Ohms
• Power Rating: 200 Watts
• Enclosure Rating: IP20 (Protected against solid objects greater than 12.5mm, but not protected against water)
• Functionality: Dissipates regenerative energy generated by the motor during deceleration phases of VFD operation.
• Compatibility: Typically used with compatible Schneider Electric Altivar VFD models. For specific VFD compatibility, consult the manufacturer's datasheet.

Applications & compatibility

This braking resistor is essential for applications where VFDs experience frequent or rapid deceleration, such as in packaging machinery, material handling systems, and automated assembly lines. It helps prevent overvoltage conditions within the VFD by providing a path for excess energy to be safely dissipated as heat, thereby protecting the drive and ensuring smooth operation of the connected motor.
