Copeland Comfort Control (White Rodgers) 3L01-350 Limit Switch

The Copeland Comfort Control (White Rodgers) 3L01-350 is a high-limit snap disc thermostat engineered for critical thermal protection in HVAC and process heating equipment. As a veteran-grade 3/4 inch snap disc limit switch, this component provides a reliable safety interface by interrupting the electrical circuit when temperatures reach the fixed 350°F cut-out threshold. Its open on rise switch action is a standard safety protocol for furnaces, duct heaters, and specialized appliance applications needing a high-temperature failsafe. Once the environment cools to the 310°F cut-in point, the internal automatic reset mechanism re-engages the circuit, ensuring continuous system readiness without manual intervention.

This 60T11-610068 limit control features 1/4 inch quick-connect terminals and a versatile loose-ring stainless steel mounting bracket for streamlined field replacement. Its rugged aluminum disc cup is designed for rapid thermal response and durability in high-ambient environments up to 350°F. Whether you are servicing a residential furnace or commercial heating unit, use this White Rodgers 3L01 series switch to maintain precise fixed temperature regulation and equipment safety standards. Its electrical ratings support a wide range of pilot duty and motor loads, making it a staple for contractors requiring high-performance HVAC temperature controls.

• Fixed Thermal Precision: Factory-set at 350°F (cut-out) and 310°F (cut-in) for consistent safety performance.
• Universal Mounting: Features a loose-ring bracket and 3/4 inch disc footprint to match standard HVAC mounting holes.
• Heavy-Duty Electrical Rating: Rated for up to 25A resistive loads and 125 VA pilot duty at 120/240/277 VAC.
• Rapid Field Service: Equipped with standard 1/4 inch tab terminals for fast wire-to-switch connections.

What does 'Open on Rise' mean for this limit switch?
The contacts break the electrical circuit when the temperature climbs to the 350°F set point, effectively shutting down the heating source to prevent overheating.

Does this switch require a manual reset button?
No, the 3L01-350 is an auto-reset model. It will automatically close the circuit and resume operation once the temperature drops back down to 310°F.

Can I use this for fan or blower control?
While 3L series switches are primarily used as high-limit safety controls, always verify your system's required temperature range. Typically, fan controls utilize 'Close on Rise' action, whereas this unit 'Opens on Rise'.
