Thermal Safety Switches efficiently detect flue gas spillage due to a blocked flue, continuous down drafting or inadequate draft condition.
THERMAL SAFETY SWITCHES
The Field Controls Thermal Safety Switch detects the increased heat generated by the flue gas spillage and deactivates the furnace or boiler. It will not allow the burner to restart until the switch has been manually reset.
WHEN DO USE A THERMAL SAFETY SWITCH?
On Barometric Draft Controls and draft hoods to detect flue gas spillage and deactivate oil and gas burners.
WHAT DOES A THERMAL SAFETY SWITCH DO?
A thermal safety switch is an electromechanical device which opens and closes contacts to control the flow of electrical current in response to temperature change. The term “Thermal Cutoff Switch” generally refers to how the switch is used.
WHAT IS A THERMAL SAFETY CUT OFF SWITCH?
A thermal safety cutoff is an electrical safety device that interrupts electric current when heated to a specific temperature. These devices may be for one-time use or may be reset manually or automatically.
NOTE: Most of Field Controls thermal safety switches are either SPDT (Single Pole Double Throw) or SPST (Single Pole Single Throw).
