Schneider Electric VW3A7730 Series Braking Resistor, For Use With Variable speed drive ATV950 - VW3A7730
This braking resistor is a Compact auxiliary device designed to absorb regenerated energy from variable-speed drives, protecting the drive and motor during deceleration phases. It is intended for use with a range of Altivar drives in industrial automation settings and provides controlled dissipation of DC bus energy to maintain stable drive operation in frequent braking cycles.
Features & Benefits
• 100Ω resistance provides predictable energy dissipation under braking
• 0.1kW average power rating for continuous 50°C operation
• Thermal protection handled by the drive to prevent overheating
• IP20 enclosure rating suitable for protected electrical cabinets
• Terminal connection capacity up to 10mm² for secure wiring
• Lightweight 1.5kg construction simplifies installation
• 0.1kW average power rating for continuous 50°C operation
• Thermal protection handled by the drive to prevent overheating
• IP20 enclosure rating suitable for protected electrical cabinets
• Terminal connection capacity up to 10mm² for secure wiring
• Lightweight 1.5kg construction simplifies installation
Applications
• Suitable as a braking resistor for ATV900 in process control
• Ideal as a braking resistor for ATV340 in machine
• Used with ATV320 variable-speed drive installations
• Can be used as a braking resistor for ATV950 wall-mount drives
• Employed as Altivar machine braking resistor accessory in automation panels
• Ideal as a braking resistor for ATV340 in machine
• Used with ATV320 variable-speed drive installations
• Can be used as a braking resistor for ATV950 wall-mount drives

What operating ambient temperatures can it tolerate?
It can operate between 0 to 50°C and be stored at -25 to 70°C.
How should it be connected to the drive DC bus?
It is wired between the DC bus Terminals (PA, PB) and the braking resistor Terminal as shown in the recommended schematic.
What mounting clearances are required?
Refer to the dimensional layout for side and front clearance and ensure free airflow within the enclosure for correct heat transfer.
What packaging and shipping unit details are available?
Single units are supplied in individual cartons with dimensions 31.5cmx17.5cmx11.5cm and grouped packs contain 33 pieces per outer package.
