Robertshaw 5300-080 Thermostat

The Robertshaw 5300-080 is a heavy-duty high temperature control designed for precise thermal regulation in commercial foodservice and industrial heating applications. This SPST (Single Pole Single Throw) thermostat operates on a break on rise configuration, opening the circuit when temperatures reach the set point. With a temperature range of 100°F to 290°F, it is a standard component for warming cabinets and ovens. The assembly features a 48-inch copper capillary and a 3/16" x 11-5/8" bulb, providing flexible routing for various cabinet geometries. Rated for 30 Amps at 250V AC, this Robertshaw thermostat replacement handles high-current resistive loads without requiring an external contactor in many setups. The 5300 series thermostat is known among technicians for its mechanical reliability and fixed 10°F differential, ensuring consistent cycle rates and thermal stability in demanding kitchen environments.

Key Benefits for Technicians

• High Ampacity Rating: The 30 Amp capacity allows for direct switching of heating elements in many 208V and 240V circuits.
• Mechanical Precision: Utilizes a specialized diaphragm for accurate calibration across the entire 100/290F temperature range.
• Durable Construction: Heavy-duty copper capillary resists corrosion and fatigue in high-heat zones.
• Standard Mounting: Designed with a universal "D" stem orientation for compatibility with most OEM and aftermarket control knobs.

Common Questions

What is the electrical configuration of the 5300-080?
This unit is an open on rise control, meaning it disconnects power to the heating circuit once the sensed temperature hits the user-defined threshold on the dial.

Can I trim the 48-inch capillary if it is too long for my application?
No. The 48-inch capillary is a sealed system containing pressurized fluid. Cutting or kinking the tube will cause immediate component failure and render the control inoperable. Excess length should be carefully coiled away from high-voltage terminals.

Is this control suitable for deep fryers?
While the Robertshaw 5300-080 is a high-limit capable control, users must verify that the 290°F maximum set point meets the specific oil temperature requirements of the appliance, as many fryers require higher thresholds.
