Built with NEMA Class II construction

ensuring the refrigerant circuit remains free of contaminants

and 120V AC circuits commonly found in residential and commercial HVAC systems

critical for achieving optimal combustion and preventing soot buildup in the heat exchanger

Carrier HH18HC196 Rollout Switch Built with NEMA Class IIThe Carrier HH18HC196 Rollout Switch is a critical safety component engineered for high heat monitoring in residential and commercial gas fired furnaces. This single pole single throw (SPST) switch is designed to detect flame rollouta dangerous condition where combustion occurs outside the heat exchangerprotecting the burner enclosure and surrounding components from thermal damage. Calibrated to a 195 degree Fahrenheit trip point, this manual reset
