Fulton Boiler 2-40-001421 Relay
The Fulton Boiler 2-40-001421 Relay is a critical LWCO relay (Low Water Cut-Off) component engineered for precise electrical switching in heating applications. This genuine OEM replacement ensures seamless integration with Fulton boiler control systems, regulating power to heating elements and ignition circuits with technical precision. Benchmarked for industrial reliability, this 4-pin boiler relay features a 10-amp switching capacity and is rated for 1/3 HP output, making it suitable for demanding 120/240VAC environments at 50/60Hz. As a cRUus certified component, it meets rigorous safety standards for high-pressure steam and hot water systems. Field technicians prioritize this specific part to maintain the integrity of the safety limit circuit, preventing system lockout and ensuring consistent boiler cycling performance. Replacing a worn relay with this factory-spec unit minimizes voltage drops and potential contact welding common in aftermarket alternatives.
Key Technical Benefits- OEM Compatibility: Specifically calibrated for Fulton boiler parts catalogs to ensure proper fitment and terminal alignment.
- High Load Rating: Robust 10A / 4.4 VA capacity designed to handle inductive loads without premature contact failure.
- Versatile Voltage Support: Dual-rated for 120VAC and 240VAC configurations, allowing for standardized stocking in service trucks.
- Safety Compliance: cRUus certification ensures the relay meets specialized industrial requirements for boiler safety controls.
- Quick Maintenance: The 4-pin interface allows for rapid troubleshooting and replacement during critical downtime windows.
What is the primary function of the 2-40-001421 in a Fulton system?
This is a low water cut-off relay used to interface between the sensing probes and the burner control circuit, ensuring the boiler shuts down if a low water condition is detected.
Can this relay be used on both 50Hz and 60Hz power supplies?
Yes, it is engineered for universal frequency compatibility, supporting global power standards for Fulton HVAC equipment.
How do I verify if this relay is the cause of a boiler lockout?
Technicians should check for continuity across the contacts and verify that the coil is receiving the proper 4.4 VA signal. If the relay fails to pull in under load, a direct OEM replacement is required.
