Description
The Emerson Climate-White Rodgers 3L09-2 Limit Switch is a temperature-controlled switching component used to manage electrical circuits based on heat conditions. It features a 1.87-inch sensing configuration and operates with an open temperature of 170F and a close temperature of 130F allowing controlled activation and deactivation of connected circuits. This switch is commonly installed in furnaces, air handling units, and burner assemblies where temperature thresholds must be monitored for safe operation. Within HVAC systems, it is positioned near heat exchange areas to respond to temperature changes and regulate system cycling in compatible control setups.
