Copeland Comfort Control (White Rodgers) 3L01-130 Limit Switch

The Copeland Comfort Control (White-Rodgers) 3L01-130 Limit Switch is a high-reliability snap disc thermostat engineered for precise thermal regulation in gas furnaces, air handlers, and HVAC heating systems. Featuring an Open on Rise switching action, this 3L01 Series limit control provides essential safety by breaking the electrical circuit when temperatures reach the 130°F fixed cut-out point. The internal snap disc mechanism ensures a crisp, positive switch action, while the auto reset function restores operation once the temperature cools to the 115°F fixed cut-in temperature. Designed for the field technician, this 3/4" disc-style switch serves as a direct HH19ZA130 cross reference, though professionals must verify specific cut-in requirements during installation. The inclusion of tab-to-screw terminal adapters and a universal mounting configuration facilitates quick on-job replacement, reducing system downtime and streamlining service calls for residential and commercial heating equipment maintenance.

• Precise Thermal Protection: Fixed 130°F opening and 115°F closing temperatures prevent equipment overheating.
• Universal Mounting: Standard 3/4" disc design ensures compatibility with a broad range of OEM HVAC parts.
• Flexible Wiring: Comes equipped with terminal adapters to accommodate both spade and screw-on connections.
• Automatic Reset: Self-resetting bipetal disc eliminates the need for manual intervention after a high-limit trip.
• Durable Construction: Built by White-Rodgers to withstand the high-cycle demands of modern furnace limit switch applications.

Is the 3L01-130 a suitable replacement for the HH19ZA130?
Yes, it is a common cross-reference; however, always verify that the 115°F cut-in (close) temperature aligns with your specific equipment's safety sequencing.

What is the maximum electrical load for this limit switch?
This 3L01 series control is typically rated for pilot duty or specific inductive/resistive loads found in 24V and 120V heating circuits; refer to the 60T11-610002 mounting flange for specific pilot duty ratings.

Can I use this switch in a cooling application?
No, this is an Open on Rise switch designed to break the circuit when it gets too hot, making it strictly a heating safety or limit control.
