PRODUCT DESCRIPTION
SCHNEIDER ELECTRIC VW3A1104R50 - Braking Resistor
This component is a dedicated braking resistor from the SCHNEIDER ELECTRIC Altivar accessory range. It is engineered to dissipate regenerative energy generated by industrial motors during deceleration phases, preventing overvoltage conditions on the DC bus of compatible variable speed drives. This unit is critical for applications requiring controlled stopping, rapid deceleration, or handling high inertia loads in industrial automation systems.
