Description
The Copeland 3L03-190 is an SPDT temperature control switch designed for precise thermal regulation in HVAC and heating applications. This control features a 190°F setpoint with a 20°F differential, allowing it to switch between contacts based on temperature changes for effective system control. The SPDT configuration provides flexibility for both normally open and normally closed circuit applications, making it suitable for fan control, limit control, or general temperature-based switching. Built with a reliable bimetal disc, the 3L03-190 delivers consistent performance and long service life in furnaces, unit heaters, and other temperature-sensitive systems.
