Field Controls GSK-160A, mV/24V Thermal Safety Switch - Auto Reset (D.I. Furnaces)

Thermal safety switches efficiently detect flue gas spillage due to a blocked flue, continuous down drafting or inadequate draft condition. With the safety switch wired in series with the burner circuit, the switch will de-energize the system's burner or burner control once it senses the spillage of hot flue gases. Available for gas-fired and oil-fired applications. Application: The GSK-160A is designed for use on draft induced furnaces. Silver Contacts. Automatic Reset Switch. How It Works: The Thermal Safety Switch detects the increased heat generated by the flue gas spillage and deactivates the furnace or boiler.
