Supco SHL515 Plenum Thermostat 160-200°F Temperature Range

The Supco SHL515 is a heavy-duty plenum thermostat designed for HVAC applications where temperature control is critical. This snap-action thermostat mounts directly in the supply air plenum to monitor air temperature and protect heating equipment from overheating conditions.

Key Features:

• Temperature range: 160°F to 200°F for high-limit protection
• Snap-action switch provides reliable on/off operation
• Compact design: 3.12" L x 1.88" W x 2.94" H for easy plenum mounting
• Bimetal sensing element for accurate temperature detection
• Automatic reset functionality when temperature drops below setpoint
• Designed for furnace and heat pump applications

This plenum thermostat acts as a safety control that opens the circuit when supply air temperature exceeds the setpoint, preventing damage to ductwork and downstream components. Commonly used as a high-limit control in residential and light commercial HVAC systems.
