The Enviro-tec PE-09-6240 is a 240°F one-time limit switch designed for HVAC heating systems and furnace safety applications. This critical safety component monitors air temperature within the furnace plenum and automatically shuts off the system when temperatures reach 240°F to prevent overheating and potential equipment damage.

Key Features:

• 240°F trip temperature rating for high-temperature protection
• One-time manual reset design requires physical intervention after activation
• CO (Cut-Out) configuration for carbon monoxide safety monitoring
• Manual reset ensures technician inspection after overheat condition
• Direct replacement for Johnson Controls part number 61F14-322802
