The Schneider Electric VW3A7710 is a braking resistor designed for use with the Altivar ATV61 and ATV71 series of variable frequency drives. This accessory is engineered to dissipate excess energy generated during regenerative braking operations, thereby protecting the drive and ensuring controlled deceleration of motor loads. Its robust construction is suitable for demanding industrial environments.

Technical details

• Series Compatibility: Altivar ATV61, Altivar ATV71
• Function: Braking resistor for energy dissipation during regenerative braking
• Purpose: Prevents overvoltage within the drive DC bus when the motor is decelerating or driven by the load.
• Construction: Designed for reliable operation in industrial settings.
• Power Dissipation: Specific wattage rating should be confirmed against the manufacturer's datasheet for your particular drive model and application requirements.
• Resistance Value: Specific resistance value should be confirmed against the manufacturer's datasheet for your particular drive model and application requirements.
• Mounting: Typically designed for direct mounting to the drive or in close proximity, refer to installation manual for precise placement.

Applications & compatibility

This braking resistor is essential for applications involving frequent or rapid deceleration of motor loads, such as those found in material handling systems, cranes, hoists, and high-inertia machinery. It ensures the safe and efficient operation of Altivar ATV61 and ATV71 drives in environments where regenerative energy needs to be managed effectively.
