The OHMITE RES350E is a wirewound rheostat, a type of variable resistor used for controlling electrical power. These devices are characterized by their robust construction and ability to handle higher power levels compared to standard potentiometers. They are commonly employed in industrial equipment, motor speed control, and other applications requiring precise and reliable resistance adjustment. Models H, J, G, K, L and RES/REL are available in enclosed or open configurations, with varying wattage ratings and shaft rotation options. Dimensions are for reference only, and factory consultation is recommended for specific requirements. These rheostats are subject to mechanical wear due to their electro-mechanical nature and have a finite lifespan.
