Fenwal 01-017002-000 Thermoswitch

The Fenwal 01-017002-000 Thermoswitch is a high-precision, slow-make-and-break thermostat designed for critical thermal control in industrial and HVACR applications. Featuring a 100°F to 400°F temperature range, this surface-mount controller utilizes differential expansion technology where the outer stainless steel shell acts as the active sensing element, providing faster thermal response than traditional probe-style units. This model serves as the direct upgraded replacement for the discontinued Fenwal 01-017000-000, transitioning from a brass construction to a more durable stainless steel housing to better withstand corrosive environments and mechanical stress. With its normally closed (NC) contacts and 5/8-inch diameter profile, it ensures reliable over-temperature protection and cycling control. This Fenwal 01-017002-000-0T equivalence ensures seamless integration for contractors maintaining legacy systems requiring precise thermal switch calibration. The 1200 series design minimizes overshoot and provides stable setpoint repeatability across the entire operating spectrum.

• Enhanced Durability: The stainless steel construction provides superior corrosion resistance and structural integrity compared to older brass models.
• Precise Thermal Response: Uses the outer shell as the sensing element for immediate reaction to temperature fluctuations.
• Drop-in Replacement: Engineered as the technical successor to the Fenwal 01-017000-000, ensuring zero-clearance mounting compatibility.
• Wide Operating Range: Adjustable 100-400 degree Fahrenheit setpoint capability for versatile field application.
• Compact Form Factor: Standard 5/8" diameter allows for installation in tight mechanical assemblies.

Common Questions:

Is the Fenwal 01-017002-000 compatible with older brass units?
Yes, this unit is the direct functional replacement for the 01-017000-000. While the housing material has changed to stainless steel, the electrical ratings and physical mounting dimensions remain compatible.

How do I adjust the temperature setpoint on this Thermoswitch?
Adjustments are made via the internal screw. Note that rotating the adjustment screw changes the contact separation point based on the expansion of the outer shell. It is recommended to calibrate the unit within the specific 100°F to 400°F range for your application.

What is the maximum electrical load for this thermal controller?
Standard 1200 series Fenwal units are typically rated for 10A at 120VAC or 5A at 240VAC, but always verify your specific system amperage requirements against the control circuit before installation.
