Eaton SVG17ED1003 Dynamic Braking Resistor 20 Ohm 500 Watt

The Eaton SVG17ED1003 dynamic braking resistor is a 20-ohm, 500-watt device designed to absorb energy generated during braking in motor-drive systems. Sold under the Cutler-Hammer brand name, this resistor is used to dissipate kinetic energy from decelerating motors in industrial applications where controlled stopping is required and drive electronics need protection from voltage spikes. The unit’s primary specs are a 20 Ω resistance and a 500 W rating, which determine how much energy it can safely convert to heat during braking events. By converting braking energy into heat, it helps limit overspeed, reduce electrical noise, and extend drive life. Common applications include industrial automation equipment, conveyors, and other machinery powered by motor drives where braking energy management is essential. This designation SVG17ED1003 in Eaton's dynamic braking resistor lineup provides a practical replacement option for service or upgrade where the 20 Ω, 500 W class is specified.
