SCHNEIDER ELECTRIC VW3E2094R350 - Braking Resistor
This component is a dedicated braking resistor designed for integration with SCHNEIDER ELECTRIC Altivar variable speed drives. Its primary function is to dissipate regenerative energy generated by motors during deceleration phases, preventing overvoltage conditions on the drive's DC bus. This ensures controlled stopping and protects the drive and motor in applications requiring rapid or frequent braking, such as material handling, lifting equipment, and high-inertia machinery.
