White-Rodgers 3L11-60 Control
The White-Rodgers 3L11-60 is a heavy-duty bimetal disc limit switch engineered for precision temperature regulation in HVAC units and commercial appliances. This 1/2" snap disc thermostat features a single pole single throw (SPST) switch configuration designed to open on rise, effectively breaking the circuit when temperatures hit the 55°F to 65°F range. As a direct replacement for the Therm-O-Disc 36T21-10842, it utilizes a high-speed contact separation mechanism for reliable cycling and extended component life. The auto reset function ensures the system recovers automatically once the temperature drops by the 20°F fixed differential. Built with a durable aluminum disc cup and stainless steel mounting brackets, this fixed temperature control includes a 1/4" loose ring and quick-connect terminations to streamline field installation for contractors. Whether you are troubleshooting air handlers or specialized machinery, the 3L11-60 provides the accuracy required for critical low-temperature limit applications.
Key Benefits for Technicians- Simplified Mounting: Features a loose ring and stainless steel brackets for versatile orientation in tight cabinets.
- High Amperage Rating: Rated for 15A at 120VAC and 10A at 240VAC, making it compatible with various resistive and inductive loads.
- OEM Compatibility: Serves as a reliable cross-reference for the 36T21-10842 and other 3L11 series limit controls.
- Rapid Response: The 1/2" bimetal disc ensures fast thermal transfer and precise "Open on Rise" switching.
What is the reset behavior of the 3L11-60?
This is an automatic reset control. It will automatically close the circuit once the temperature falls approximately 20°F below the opening setpoint.
Can I use this to replace a manual reset limit?
No. For safety-critical limit applications where a manual reset is required by the equipment manufacturer, do not substitute an auto-reset switch like the 3L11-60.
What are the terminal specifications?
The unit is equipped with standard 1/4" male quick-connect terminals, which are the industry standard for most furnace and appliance wiring harnesses.
