The OHMITE RHL35RE is a wirewound rheostat, a type of variable resistor used for controlling electrical power. These devices are commonly employed in industrial machinery, motor speed control, and audio equipment where precise and reliable resistance adjustment is required. The RHL35RE series is known for its robust construction and ability to handle significant power dissipation. Due to their mechanical nature, these rheostats have a finite lifespan and are subject to wear. Refer to catalog #203 for comprehensive specifications and application guidelines.
