Robertshaw 5300-766 Thermostat

The Robertshaw 5300-766 is a professional-grade electric thermostat engineered specifically for high-temperature commercial applications such as ovens, griddles, and deep fryers. This KX-series thermostat operates within a temperature range of 200°F to 400°F, providing precise thermal regulation for heavy-duty kitchen equipment. Utilizing a 24-inch stainless steel capillary and a 3/16" x 11-5/8" bulb, this unit ensures accurate temperature sensing even in high-heat environments. The 5300-766 Robertshaw model is a pilot duty thermostat, designed to act as a control circuit switch rather than a power-switching device. It features a specialized stuffing box (SB) for secure penetration into pressurized or liquid-filled tanks. When performing a commercial kitchen thermostat replacement, this SPST (Single Pole Single Throw) control offers the reliability required for consistent heat cycles and minimal thermal overshoot in professional food service environments.

• Industrial Durability: The stainless steel bulb and capillary resist corrosion and thermal fatigue in demanding kitchen environments.
• Precision Calibration: Factory-calibrated for the 200°F to 400°F range to maintain strict food safety and cooking standards.
• Versatile Mounting: Includes a stuffing box configuration, making it ideal for deep fryer and autoclave applications where a gas-tight or liquid-tight seal is mandatory.
• OEM Compatibility: Serves as a direct replacement for various high-limit and primary temperature controls in commercial cooking lines.

What is the electrical rating for this pilot duty control?
This unit is designed for pilot duty applications, typically rated at 125VA at 120/240V AC. It should be used to signal a contactor or gas valve rather than carrying the full amp load of heating elements.

How do I handle the 24-inch capillary during installation?
Ensure the 24-inch capillary is routed away from sharp edges and avoid kinking the line, as any restriction in the fluid flow within the tube will result in inaccurate temperature readings or total component failure.

Can this thermostat be used for water heating applications?
While the stainless steel construction and stuffing box allow for liquid immersion, the 200°F to 400°F range is generally too high for standard domestic hot water, making it best suited for oils and high-temp commercial fluids.
