Lennox 15D60 Fan Relay
The Lennox 15D60 Fan Relay is a critical OEM electrical control component engineered for heavy-duty fan cycles in Lennox air handlers and condensing units. Operating on a 208/240V AC coil (50/60 Hz), this HVAC control relay is the direct performance replacement for Lennox 104774-01 and the legacy 76700525. Designed for continuous duty, it features a UL Class B (130°C) coil insulation rating, ensuring stability in high-ambient control cabinets where temperatures range from -40°F up to 150°F. The internal switching mechanism utilizes fine silver contacts with gold plating, which prevents oxidation and secures high conductivity during low-current logic signals or full-load amperage draws. This SPNO/SPNC fan relay ensures precise sequencing for blower motors and auxiliary circuits, maintaining the integrity of the original system design and optimizing airflow management in commercial or residential configurations.
Technical Performance Features
- Genuine OEM Compatibility: Direct drop-in for Lennox 15D60, 104774-01, and 76700525 part numbers.
- High-Conductivity Contacts: Gold-plated silver contacts minimize resistance and contact pitting.
- Industrial Temperature Rating: Reliable operation in extreme environments from -40°F to 150°F.
- Electrical Versatility: Supports contact ratings of 3A at 277VAC and up to 277VA inductive loads.
- Compact Footprint: 3" W x 1.5" H frame allows for easy integration into crowded electrical panels.
Common Questions
Is the 15D60 relay compatible with 120V systems?
No, this specific model is designed for 208/240V AC coil applications. Using this on a 120V circuit will result in failure to pull the contacts, while 480V will damage the coil instantly.
Can I use the Lennox 15D60 to replace a 76700525?
Yes, the 15D60 is the official manufacturer-designated superseding part for the 76700525, ensuring identical mounting and electrical specs.
What is the benefit of gold-plated contacts in this HVAC relay?
The gold plating provides a "wiping" action that prevents surface corrosion, which is vital for relays that may sit idle or operate in high-humidity environments.
