The Schneider Electric VW3A7751 is a braking resistor designed for use with variable frequency drives (VFDs) in industrial automation systems. This component is engineered to dissipate excess energy generated during regenerative braking operations, preventing overvoltage conditions within the drive. It is part of the Schneider Electric Altivar series, commonly integrated into machinery requiring precise speed control and frequent deceleration.

Technical details

• Product Type: Braking Resistor
• Resistance: 60 Ohms
• Power Rating: 3.4 kW
• Enclosure Rating: IP20
• Series Compatibility: Altivar (verify specific drive compatibility with manufacturer datasheet)
• Function: Dissipates regenerative energy during braking
• Application Context: Used in conjunction with variable frequency drives to manage braking torque and prevent overvoltage

Applications & compatibility

This braking resistor is essential for applications where VFDs experience significant regenerative energy feedback, such as in material handling systems, elevators, cranes, and high-inertia loads. It ensures stable operation and protects the VFD from potential damage caused by voltage spikes during deceleration cycles. Compatibility should be verified with the specific Schneider Electric Altivar drive model.
