The Schneider Electric VW3A7813 is a braking resistor designed for use with variable frequency drives (VFDs) to dissipate excess energy during deceleration. This component is integral to VFD systems that experience frequent braking or require rapid stopping of motor loads, helping to protect the drive from overvoltage conditions. It is engineered to handle significant power dissipation, ensuring the reliable operation of motor control systems.

Technical details

• Series: VW3A (Schneider Electric Altivar VFD Accessories)
• Resistance: 2.1 Ohms
• Power Rating: 112 kW (kilowatts)
• Enclosure Protection: IP23 (protected against solid objects larger than 12.5mm and against water spray from any direction)
• Function: Braking resistor for VFD energy dissipation
• Application: Designed for use with compatible Schneider Electric Altivar VFDs to manage regenerative energy during motor deceleration.
• Voltage Compatibility: Specific voltage class should be verified against the compatible VFD model and manufacturer datasheet.

Applications & compatibility

This braking resistor is commonly employed in industrial automation applications where motors require frequent or rapid deceleration, such as on packaging lines, material handling systems, and machine tools. It is compatible with Schneider Electric Altivar variable frequency drives that support external braking resistor configurations. Proper selection depends on the VFD model, motor size, and braking duty cycle.
