Copeland Comfort Control (White Rodgers) 3L01-165 Limit Switch

The Copeland Comfort Control (White Rodgers) 3L01-165 Limit Switch is a professional-grade snap disc auto-reset limit switch engineered for high-limit safety and fan control in HVAC systems and industrial appliances. This 3/4-inch diameter thermostatic control utilizes a 60T11-610069 design to provide reliable thermal protection. With a fixed cut-out temperature of 165°F and a fixed cut-in of 125°F, this open-on-rise limit switch effectively interrupts the electrical circuit upon reaching the high-temperature threshold, automatically resetting once the system cools. Designed for versatility, the 3L01-165 features 1/4-inch quick-connect terminals and is rated for 120/240/277 VAC applications. Whether you are servicing a furnace, heat pump, or commercial blower, this OEM-spec high-limit thermostat ensures exact calibration and system longevity under demanding conditions. Its SPST switch action and compact snap-action disc mechanism make it a standard replacement for many standard temperature-regulated safety circuits.

• Precision Temperature Regulation: Features a 165°F cut-out to prevent equipment overheating and a 125°F cut-in for automatic system recovery.
• OEM Compatibility: Replaces White Rodgers 3L01-165 and 60T11-610069 models, meeting strict safety standards for HVAC and appliance duty.
• High Electrical Capacity: Rated for up to 25 Amps resistive and 125VA pilot duty, suitable for both 120V and 240V/277V systems.
• Durable Construction: Built with a 3/4" snap disc and 1/4" quick-connect terminals for a secure, vibration-resistant installation.
• Efficient Safety Cycling: The open-on-rise logic serves as a critical safety switch to protect heating elements and motors from excessive thermal load.

What does "Open on Rise" mean for this switch?
In HVAC applications, open on rise indicates that the internal contacts will separate (breaking the circuit) when the temperature climbs to 165°F, stopping the heating source for safety. The contacts close again (completing the circuit) when the temperature drops to 125°F.

Is the 3L01-165 compatible with my furnace blower?
This 3L01-165 limit switch is commonly used as a fan control or high-limit safety in many gas and electric furnaces. Always verify the temperature ratings on your existing switch prior to replacement to ensure the 165°F/125°F range matches your equipment specifications.

Can this be used in 277V commercial systems?
Yes, the 3L01-165 is rated for 120/240/277 VAC, making it suitable for a wide variety of residential and commercial HVAC units.
