The Supco SLS180 is an automatic reset rollout switch designed to provide critical overheat protection for furnaces and heating appliances. This safety switch automatically cuts power when flue gases exceed safe temperatures, preventing dangerous rollout conditions.

Key Specifications:

• Cut out temperature: 180°F - automatically opens circuit when temperature exceeds safe limits
• Cut in temperature: 140°F - automatically resets and closes circuit when temperature drops to safe level
• 45-degree angle mounting configuration for optimal positioning in tight installations
• 1/4 inch male blade terminals for secure electrical connections
• Automatic reset function eliminates need for manual intervention after trip
• Bimetal disc sensing element provides reliable temperature detection

This rollout switch is commonly used as a replacement safety component in residential and light commercial gas furnaces, where it monitors flue temperatures and protects against improper venting or burner flame rollout. The automatic reset feature allows the system to resume normal operation once safe temperatures are restored, while still providing essential safety protection.
