White-Rodgers 3L01-250 Limit Switch

The White-Rodgers 3L01-250 Limit Switch is a high-performance snap disc limit control engineered for critical temperature regulation in HVAC furnaces, heat pumps, and high-intensity infrared heaters. Designed for open on rise switch action, this SPST (Single Pole Single Throw) safety control features a fixed 250 degree F cut-out and a 210 degree F cut-in, ensuring precise thermal protection for blowers and fan systems. As a direct 3/4 inch snap disc replacement with a 60T11-610023 Therm-O-Disc style, it simplifies field service by matching standard mounting footprints. Its automatic reset limit switch functionality and aluminum disc cup provide consistent 120/240/277 VAC performance under high-duty cycles. Featuring 1/4 inch quick-connect terminations and a stainless steel loose ring bracket, this White-Rodgers furnace limit switch offers the durability required for industrial and residential applications where high-speed contact separation is essential for equipment safety.

Key Benefits

• Precise Thermal Safety: Fixed 250 degree F cut-out prevents over-temperature conditions in critical HVAC safety control applications.
• Universal Compatibility: Slotted 3/4 inch mounting holes and included tab-to-screw adapters facilitate quick on-job replacements for diverse equipment.
• Durable Construction: Features an aluminum disc cup and stainless steel brackets for long-term reliability in high-heat environments.
• Automatic Reset: Includes an auto-reset snap disc mechanism that restores circuit continuity once temperature drops to the 210 degree F cut-in point.
• High Electrical Capacity: Rated for up to 25A in non-inductive applications and versatile pilot duty across 120V, 240V, and 277V systems.

Common Questions What is the difference between an 'L' and 'F' White-Rodgers control? In White-Rodgers nomenclature, 'L' stands for Limit (Open on Rise), while 'F' stands for Fan (Close on Rise). The last three digits, like the 250 in this 3L01-250, indicate the cut-out temperature for limit controls. How does an open on rise switch operation work in a furnace? An open on rise limit switch acts as a safety breaker; when the plenum temperature reaches the 250 degree F threshold, the contacts snap open to cut power to the gas valve or heating element, preventing damage. Can I use the 3L01-250 to replace a 60T11-610023 limit? Yes, the White-Rodgers 3L01-250 is the standard professional replacement for the 60T11 style 610023, utilizing the same bimetal sensing technology and 3/4 inch disc physical specifications.
