Ohmite RJS300E Wirewound Rheostat The OHMITE RJS300E is a wirewound rheostat, a type of variable resistor used for precise control in industrial applications. These rheostats are electro-mechanical devices, subject to mechanical wear and therefore have a finite life. They are available in various configurations with different wattage ratings, core types (open or enclosed), and shaft rotation options. Refer to catalog #203 for detailed specifications and ordering information.
