The Schneider Electric VW3A7745 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 motor deceleration, preventing overvoltage conditions within the drive. It is a critical accessory for applications requiring frequent or rapid stopping of motor loads, such as those found in material handling and machine tool operations.

Technical details

• Series: VW3A7745
• Type: Braking Resistor
• Resistance: 8 Ohms
• Power Rating: 3.8 kW
• Enclosure Protection: IP23
• Function: Energy dissipation during motor deceleration
• Application: Overvoltage protection in VFD systems

Applications & compatibility

This braking resistor is commonly employed in conjunction with Schneider Electric Altivar variable frequency drives to manage braking energy. It is suitable for applications where dynamic braking is required, including packaging machinery, conveyor systems, and automated assembly lines. The IP23 rating indicates protection against solid objects larger than 12.5mm and water spray at an angle up to 60 degrees from the vertical.
