Description
The Robertshaw 5500-103 Infinite Switch with Black Dial is a power control component that is used to control the output of heating elements in HVAC systems. It is 120V and the resistive control is adjusted to electrical delivery to the load in small steps. This is installed in control panels or user interfaces and connected to the heating circuit to regulate energy applied to elements. It plays a vital role of facilitating variable heat levels, controlled temperature response, and constant operation behavior.
