Robertshaw 5210-363 Thermostat

The Robertshaw 5210-363 is a heavy-duty, direct-acting commercial electric thermostat engineered for high-temperature precision and industrial reliability. Featuring a Single Pole Single Throw (SPST) configuration, this B10 series control is a "slow make and break" device designed to maintain tight temperature differentials in critical equipment. With a broad temperature range of 150°F to 550°F (66°C to 288°C), it is the standard for contractors servicing commercial kitchen appliances, laboratory ovens, and sterilization units. The assembly includes a 72-inch nickel-plated copper capillary and a 3/16” x 10-7/8” sensing bulb that provides exceptional sensitivity to thermal fluctuations. Rated for 20 Amps at 120V AC or 15 Amps at 240V AC resistive loads, this Robertshaw thermostat ensures consistent switch action via fine silver contacts. Whether you are performing a thermostat replacement on a steam table or optimizing an incubator’s thermal curve, the 5210-363 provides the rugged, high-temperature thermostat performance required for professional HVACR and food service applications.

• Precision Thermal Control: Engineered with a slow make and break design to provide a close temperature differential for sensitive applications.
• Industrial Durability: Equipped with fine silver contacts and a rugged housing to withstand high-cycle commercial use.
• Extended Reach: The 72-inch nickel-plated capillary allows for flexible mounting and bulb placement in deep or recessed equipment.
• Broad Compatibility: Rated for both 120V and 240V AC resistive loads, making it a versatile HVAC part for various electrical configurations.
• High-Heat Capacity: Specifically calibrated for extreme environments requiring a 550 degree thermostat limit.

Is the dial included with this commercial thermostat?
Yes, the 5210-363 typically includes a 4-way 1-10 reference dial to allow for accurate temperature setpoint adjustments by the technician.

Can this be used for residential water heaters?
While technically an electric thermostat, this model is designed for commercial and industrial cookery and laboratory equipment with higher temperature requirements than standard domestic water heaters.

What is the sensing bulb made of?
The sensing bulb and capillary are constructed from nickel-plated copper, offering excellent thermal conductivity and resistance to corrosion in high-heat environments.
