The OHMITE RHS100E is a wirewound rheostat, a type of variable resistor used to control electrical current. These rheostats are characterized by their robust construction and ability to handle higher power levels compared to other potentiometer types. They find applications in industrial equipment, motor speed control, and laboratory instrumentation where precise and reliable resistance adjustment is required. Models H, J, G, K, L and N are listed under UL File No. E-10946 and CSA File No. 21309. All rheostats are 10% tolerance.
