White-Rodgers 3F01-150 Switch

The White-Rodgers 3F01-150 is a heavy-duty 3/4" snap disc fan control engineered for precision cycles in forced-air heating systems. This SPST fan switch features a close on rise action, designed to activate the blower motor once the heat exchanger reaches a 150°F cut-in temperature. To maintain system efficiency and prevent cold drafts, the switch provides an auto-reset function that interrupts power when the temperature drops to the 130°F cut-out setpoint. For contractors handling field replacements, the 60T12-610050 style construction includes an integral oval flange for universal mounting and 0.25-inch quick-connect terminals, ensuring compatibility with most residential furnace blowers and industrial air handlers.

• Universal Compatibility: Standard 3/4-inch diameter and mounting holes match the industry-standard footprint for fast field replacement.
• Terminal Flexibility: Includes tab-to-screw terminal adapters to accommodate both legacy screw-down and modern quick-connect wiring.
• Robust Electrical Ratings: Rated for 10A at 120VAC and 5A at 240VAC, supporting a wide range of blower motor loads.
• Automatic Reset: Eliminates manual intervention by automatically cycling the fan based on real-time temperature feedback.

What is the difference between a 'Fan' and 'Limit' switch in the 3F01 series?
In White-Rodgers nomenclature, "F" (like the 3F01-150) denotes a Fan Control which closes on temperature rise to turn on a blower. "L" denotes a Limit Control which opens on rise to shut down a burner for safety.

Can I use this switch for a 240V motor?
Yes, this snap disc thermostat is rated for 5A at 240VAC and 10A at 120VAC, making it suitable for various line-voltage applications.

Does this part include the adapter plate?
The switch features an integral flange, but if your specific application requires a specialized adapter plate like the F6-1798, it must be sourced separately.
