Breaker Honeywell 45900404-006B (double reserve) Original double adapter for safe connection of thermocouple and draft control sensors Breaker Honeywell 45900404-006B (double reserve) is a specialized original component for automation systems of gas heating equipment. This device is installed in the thermocouple circuit and, as a rule, integrates with a draft control sensor. In case of draft sensor activation or pilot flame extinction, the breaker instantly de-energizes the solenoid valve, stopping gas supply. Technical specifications Part numbers: 45900404-006B, 534.601.900 Manufacturer: Honeywell (Europe/USA) Type: Double reserve (adapter) Design: With two threaded ports for connecting an additional sensor (e.g., safety thermocouple or draft sensor) Application: Gas boilers, water heaters and heat generators Key advantages Original Honeywell component: Full compliance with factory specifications ensures correct electrical resistance and connection tightness. Built-in dual-channel protection: Allows connection of both the main thermocouple and an additional flue gas exhaust control sensor (draft sensor), increasing operational safety. Installation versatility: Adapter design allows convenient insertion of a draft sensor into the thermocouple line in cramped boiler equipment conditions. Signal stability: Ensures reliable transmission of micro-signal from thermocouple to gas valve even with an additional break. Operating principle and signs of malfunction The "double reserve" functions as a standard circuit breaker but has an additional input for connecting safety sensors. How it works: Micro-voltage from the thermocouple is sequentially
