The Schneider Electric VW3A7743 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 the deceleration of motor loads, thereby protecting the VFD from overvoltage conditions. It is a critical component for applications requiring rapid motor stopping or frequent speed changes.

Technical details

• Product Type: Braking Resistor
• Resistance: 16 Ohms
• Power Rating: 2.2 kW
• Enclosure Rating: IP20
• Manufacturer Series: VW3A Series (compatible with Schneider Electric Altivar drives)
• Functionality: Dissipates regenerative energy from motor deceleration
• Application: Prevents VFD overvoltage during braking

Applications & compatibility

This braking resistor is commonly integrated into systems utilizing Schneider Electric Altivar variable frequency drives, such as those found in packaging machinery, material handling equipment, and machine tool applications. Its IP20 rating makes it suitable for installation within control cabinets where protection against solid objects greater than 12.5mm is required.
