Thermocouple circuit breaker Honeywell 45900414-004 (long reserve) Original safety element for quick emergency shutdown of gas equipment Thermocouple circuit breaker Honeywell 45900414-004 (also known as long reserve or adapter) is an original component used in flame control systems of gas boilers, water heaters and burners. It is designed for installation between the thermocouple and the solenoid valve (gas valve). In emergency situations (overheating, flame roll-out, lack of draft) this breaker opens the electrical circuit, instantly shutting off the gas supply, preventing accidents. If your equipment does not hold flame or the gas valve shuts off without apparent reason, the problem often lies in a malfunction of this element. Technical specifications Part numbers: 45900414-004, 534.601.004 Manufacturer: Honeywell (USA/Europe) Type: Thermocouple circuit breaker, reserve (adapter) Size: Long reserve (design intended for installation on units with increased distance to the gas valve) Application: Connecting thermocouple to gas valve with extended connection Key advantages Original compatibility: Full compliance with factory specifications of Honeywell and most imported thermocouples, ensuring correct resistance in the circuit. Operational safety: Guarantees quick activation of the safety system when thermocouple temperature drops or draft control sensors trigger. Connection tightness: Provides reliable mechanical and electrical connection between thermocouple and valve, preventing gas leaks and arcing in the circuit. Ease of installation: Long threaded part ("long reserve") is ideal for retrofitting and repairing equipment with deep mounting
