Lochinvar & A.O. Smith 100289379 Circuit Breaker
The Lochinvar & A.O. Smith 100289379 Circuit Breaker is a critical 5 Amp protection component engineered for high-output commercial boilers and water heating systems. As a veteran technician knows, maintaining the integrity of the control circuit is paramount for preventing nuisance trips and protecting sensitive electronic boards. This 5 Amp thermal circuit breaker is specifically utilized in the control panel assembly of Lochinvar Power-Fin models, including the 1802 and 2072 series, as well as compatible A.O. Smith commercial units. It provides a reliable disconnect point to safeguard HVAC control wiring and secondary transformer circuits from overcurrent conditions that can lead to costly component failure.
Designed for precise fitment, the 100289379 ensures that your 120V to 24V control logic remains stable under standard operating loads. When diagnosing a unit that won't initiate its ignition sequence, checking this OEM replacement circuit breaker is a standard first step. Utilizing genuine Lochinvar boiler parts like this breaker maintains the original engineering specifications of the appliance, ensuring the trip curve matches the inductive loads of the internal relays and contactors. For contractors managing large-scale hydronic systems, keeping this 5A circuit protector in the service truck is essential for reducing emergency downtime.
Key Benefits- Precise Overcurrent Protection: Calibrated specifically to a 5 Amp threshold to protect high-value primary and secondary control circuits.
- OEM Compatibility: Guaranteed fit for Lochinvar Power-Fin 1802-2072 models and equivalent A.O. Smith commercial water heaters.
- Field-Service Efficiency: Simple integration into the existing control panel allows for rapid restoration of boiler functionality.
- Rugged Construction: Built to withstand the high ambient temperatures common within commercial mechanical room environments.
What causes this 5 Amp breaker to trip frequently?
Frequent tripping is often indicative of a short in the 24V control loop, a failing contactor coil, or an overloaded transformer. Always ohm out your 24V components before replacing the breaker to ensure a downstream fault isn't the root cause.
Can I replace the 100289379 with a standard glass fuse?
No. This component is designed as a manual or thermal reset breaker specific to the manufacturer’s control housing. Swapping it for a different protection type can compromise the safety circuit and lead to improper trip timing.
Is this breaker compatible with all Power-Fin models?
While used across many high-BTU units, it is primarily specified for the 1802 and 2072 series. Always verify your specific model and serial number against the parts manual as amp ratings for control circuits vary between smaller and larger chassis.
