Thermocouple interrupter SIT 0.974.402 (M9x1) — original safety element for gas boilers Thermocouple interrupter SIT 0.974.402 (also known as eco-connector or circuit breaker) from Italian manufacturer SIT Group is a crucial safety component for flued gas boilers. It is connected in the electrical circuit between the thermocouple, draft sensor and electromagnetic valve. Key features: Thread: M9x1 (external × internal) Type: Thermocouple interrupter (thermal circuit breaker) Purpose: Protection against draft failure in the flue Material: High-quality brass with temperature-sensitive elements Compatibility: SIT automation (Eurosit, Sigma, etc.) Why buy thermocouple interrupter SIT 0.974.402? This element provides an additional level of protection for your gas equipment. In the absence of normal draft in the flue (blockage, backdraft, ventilation problems) the thermocouple interrupter opens the electrical circuit, instantly shutting off the gas supply. This prevents accumulation of carbon monoxide in the room and protects your family. Advantages of original SIT spare part: Italian quality — proven reliability of the world leader in gas automation Precise M9x1 thread for convenient and leak-proof connection Easy installation — direct replacement without modifications Durability and stable operation under continuous operation Compatibility with most Russian and European floor-standing boilers For which equipment is it suitable? Thermocouple interrupter SIT 0.974.402 is ideal for: Floor-standing gas boilers with SIT automation (Lemax, Siberia, Rostovgazoapparat, Borinskoye, etc.) Boilers ZHMZ and other manufacturers with M9x1 connection Systems with draft sensor (thermocouple interrupter) Ensure maximum safety of your heating system!
