Thermocouple interrupter SIT 0.974.401 from Italian manufacturer SIT Group is an important safety component for flued gas boilers. It is used in pair with a draft sensor and serves as a reliable intermediary in the electrical circuit: thermocouple — draft sensor — electromagnetic valve. Key features: Thread: M8x1 (external × internal) Type: Thermocouple interrupter (thermal circuit breaker) Purpose: Protection against draft failure in the flue Material: High-quality brass and temperature-sensitive elements Compatibility: Full with SIT automation (Eurosit, Sigma, etc.) Why buy thermocouple interrupter SIT 0.974.401? This element provides an additional level of safety for your gas boiler.
