Robertshaw 5300-770 Temperature Control

The Robertshaw 5300-770 is a heavy-duty pilot duty thermostat engineered for high-temperature commercial cooking and heating applications. This snap-acting SPST thermostat features a precise temperature range of 175°F to 500°F (80°C to 260°C), making it a standard choice for vulcan fryers and gas-fired commercial equipment. Designed for durability, the unit utilizes silver contacts and a 60-inch capillary tube with a 3/16" x 11-5/8" nickel-plated bulb to ensure rapid response and sustained accuracy in demanding environments.

As a KX series pilot duty model, this control is rated for 50VA at 120/277V AC. The mechanism is direct acting, meaning it opens on temperature rise, providing reliable cycling for burners or heating elements. Technicians will appreciate the 1-3/16" stem length with a flat-down position for standard dial compatibility. The compact design and rugged housing are built to withstand ambient temperatures up to 200°F, ensuring long-term performance in hot kitchen lines or industrial enclosures.

• Precision Temperature Control: Wide 175°F to 500°F range suitable for versatile commercial kitchen equipment.
• Extended Reach: Includes a 60-inch capillary tube for flexible mounting away from the primary heat source.
• Industrial Durability: Equipped with rugged silver contacts to prevent pitting and maintain electrical conductivity.
• Accurate Calibration: Features a 12°F mechanical differential for tight temperature swings and consistent output.
• OEM Compatibility: Replaces factory parts for Vulcan, Hobart, and Garland systems, including part numbers like 411506-3.

• What is the electrical rating for this pilot duty thermostat? It is rated for 50VA Pilot Duty at 120/277V AC. It is not intended for high-amperage resistive loads without a contactor.
• How do I calibrate the 5300-770? Calibration can be adjusted using the small screw on the stem; a 1/4 turn typically equals approximately 12°F–18°F depending on the specific application setting.
• Is the capillary tube susceptible to moisture? While the rugged design handles high heat, avoiding sharp kinks in the 60" line is critical to preventing diastat failure.
