Fulton Boiler 2-40-001021 Relay
The Fulton Boiler 2-40-001021 Relay is a specialized Low Water Cutoff (LWCO) control engineered to maintain critical safety parameters in legacy Fulton steam and hydronic systems. This 11-pin plugin relay operates on 120VAC at 50/60 Hz and integrates a dedicated test function, allowing technicians to verify circuit interruption without draining the system. Designed as a high-reliability safety interlock, the 2-40-001021 utilizes NO/NC powered contacts to provide a positive disconnect during low water conditions, preventing catastrophic dry-fire scenarios. With a nominal 4.4 VA no-load power draw, it offers efficient monitoring for aging boiler plants where OEM specified replacements are required to maintain the original control logic and UL listing of the equipment. As a discontinued OEM part (also referenced by part numbers 240001021 and 2401021), this relay is a vital component for mechanical contractors tasked with the repair and maintenance of industrial Fulton boilers.
Key Benefits for Contractors:
- System Integrity: Ensures precise low water cutoff timing and response, matching the original engineering specifications of the Fulton pressure vessel.
- Simplified Diagnostics: The integrated test function allows for rapid field verification of the relay’s internal logic and contact state.
- Drop-in Replacement: The standard 11-pin configuration ensures a direct fit into existing relay bases, reducing labor time during emergency service calls.
- Versatile Signaling: Features Normally Open and Normally Closed contacts for simultaneous burner shutdown and alarm circuit activation.
- OEM Reliability: Built to handle the high-cycle demands and thermal environments common in industrial boiler rooms.
Common Questions:
Is the Fulton 2-40-001021 compatible with newer Fulton Pulse or VMP models?
This specific relay is typically found in legacy systems. Always verify the wiring schematic on the cabinet door to ensure the 11-pin base and 120V coil voltage match the 2-40-001021 specifications before installation.
What are the alternative part numbers for this LWCO relay?
You may find this unit listed as 240001021 or 2401021. These are interchangeable with the standard Fulton 2-40-001021 designation.
Can I test the relay without a low water condition?
Yes, the built-in manual test function is designed specifically for this purpose, allowing you to cycle the LWCO relay to confirm the burner circuit breaks as intended.
