The OHMITE RHS75RE is a wirewound rheostat, a type of variable resistor commonly used in industrial applications requiring precise control of electrical circuits. These rheostats are known for their durability and ability to handle higher power levels compared to standard potentiometers. They are suitable for applications such as motor speed control, lighting dimming, and volume adjustment in audio equipment. Models H, J, G, K, L and RHS75RE are listed under UL File No. E-10946 and CSA File No. 21309. All rheostats are 10% tolerance.
