Fenwal 08-033024-106 Limit Switch

The Fenwal 08-033024-106 Limit Switch is a mission-critical surface mount snap disc thermostat designed for high-temperature thermal protection. This SPST (Single Pole Single Throw) control is engineered to open the electrical circuit at 500°F and provides an auto reset function once the temperature cools to 440°F. Built for the rigorous demands of industrial heating and commercial HVACR applications, this Fenwal 08-033024-106 ensures precise high-limit safety control by preventing equipment overheating. The snap-action bimetallic disc delivers a rapid, positive break of the circuit, minimizing arcing and maximizing the component's operational life. Whether used in furnace plenums, industrial ovens, or specialized heat exchangers, this switch provides the automatic temperature reset required to maintain system uptime without manual intervention. Its compact surface-mount configuration allows for direct integration onto heat-sensitive surfaces for immediate thermal response.

Key Benefits for HVACR Applications

• Precise Thermal Cutout: Factory-calibrated to open at 500°F, protecting expensive heat exchangers and sensitive downstream components.
• Automatic System Recovery: Features an auto reset thermostat mechanism that closes at 440°F, eliminating service calls for manual resets.
• Durable Snap-Action Design: The snap disc limit switch construction ensures a clean electrical break, reducing wear on contact points.
• Universal Surface Mounting: Designed for easy installation on flat or curved surfaces, making it a versatile replacement HVAC limit switch.
• High-Temperature Rating: Specifically built for high-heat environments where standard residential limit switches would fail.

Common Questions

What is the maximum operating voltage for this Fenwal switch?
This Fenwal 08-033024-106 is typically rated for standard HVAC control voltages (24V) as well as line voltage applications up to 120-240VAC, depending on the specific resistive load requirements of your system.

Is this switch a suitable replacement for manual reset limits?
No, this is an auto reset limit switch. If your safety protocol or local mechanical code requires a manual reset for high-limit protection, this component should not be used as a primary safety replacement in those specific instances.

Can this be mounted in any orientation?
Yes, as a surface mount snap disc, it can be mounted horizontally or vertically. For the most accurate temperature sensing, ensure the metal disc makes firm, flush contact with the surface being monitored.
