White-Rodgers 3L01-150 Limit Switch

The White-Rodgers 3L01-150 is a heavy-duty, 3/4-inch snap disc limit switch designed for critical temperature regulation in residential and commercial HVAC systems. This automatic reset limit control features a fixed 150°F cut-out and a 110°F cut-in, ensuring precise high-limit safety by opening the electrical circuit on temperature rise. Engineered as a SPST fan limit control, the 3L01-150 serves as a direct replacement for 3D01-8 and 60T11-610009 models, offering broad compatibility across various furnace and air handling units. Its rugged construction includes stainless steel mounting brackets and an aluminum disc cup for rapid thermal response. The unit is rated for multi-voltage applications (120V, 240V, and 277V) and supports up to 25 Amps resistive load, making it a reliable furnace high limit switch for field-service contractors requiring a "drop-in" HVAC replacement part with consistent performance across high-cycle operations.

• Universal Compatibility: Direct replacement for White-Rodgers 3D01-8 and industry-standard 3/4" disc footprints.
• Reliable Safety: Fixed 150°F cut-out ensures equipment protection by breaking the circuit on temperature rise.
• Automatic Reset: Self-resetting functionality at 110°F eliminates manual intervention after a thermal event.
• Versatile Electrical Ratings: Supports 120/240/277 VAC with a 25.0A resistive rating at 120/240V.
• Rugged Build: Features stainless steel surface mounting brackets for secure installation in high-heat environments.

What does 'Open on Rise' mean for the 3L01-150?
This indicates the switch is normally closed and will break (open) the electrical circuit when the sensed temperature reaches the 150°F limit, effectively shutting down the burner or heat source for safety.

Can I use this to replace a manual reset limit switch?
No, this model features an auto-reset snap disc. Always match the reset type of the original OEM specification to maintain the safety integrity of the appliance.

Is the mounting bracket adjustable?
The 3L01-150 comes with standard fixed stainless steel mounting ears designed for 3/4-inch disc configurations, providing a flush mount for optimal thermal contact.
