Copeland Comfort Control (White Rodgers) 3L02-200 Limit Switch

The Copeland Comfort Control (White Rodgers) 3L02-200 Limit Switch is a high-limit safety control engineered for precise temperature regulation in residential and commercial HVAC systems. This snap disc manual reset switch is rated for a 200°F fixed cut-out and utilizes an open on rise switch action to prevent equipment overheating. As a direct 460-500-000 replacement, it is frequently used by technicians for flanged airstream mounting in air handlers and furnaces. The SPST operation ensures reliable electrical interruption with a motor full load rating of 10A at 120VAC and 5A at 240VAC. Built for durability, this manual reset limit switch serves as a critical safety component to protect blowers and heat exchangers from thermal damage. When troubleshooting a high limit switch tripped condition, this OEM-quality component provides the exact thermal response required for safe system resumption following a manual override.

Key Benefits for Contractors:

• Universal flanged airstream mount design allows for versatile installation in various duct and plenum configurations.
• Standardized 3L02-200 specifications provide a drop-in solution for legacy White Rodgers 60T15-330538 controls.
• High-temperature 200-degree fixed cut-out protects heat exchangers from cracking due to airflow restrictions.
• Manual reset mechanism ensures technicians must inspect the system before restarting, enhancing overall safety.
• Compatible with pilot duty circuits up to 125 VA at 120/240/277 VAC.

Common Questions:

Can I use the 3L02-200 as an automatic reset switch?
No. This is a manual reset limit switch. For safety reasons, it requires a physical button press to close the circuit after a 200°F trip occurs, ensuring the cause of the overheat is addressed.

How do I verify if my current 460-500-000 is failing?
Check for continuity across the terminals when the system is cool. If the circuit is open at room temperature and the manual reset button is depressed, the internal snap disc or SPST contacts may be compromised.

What is the proper mounting orientation for this limit control?
The flanged mount is designed for airstream sensing. Ensure the disc is positioned directly in the path of the air to accurately monitor the high limit temperature threshold.
