Robertshaw 5210-125 Thermostat

The Robertshaw 5210-125 is a heavy-duty Type B10 series electric thermostat engineered for precise temperature regulation in commercial cooking and laboratory environments. This direct-acting thermostat utilizes a slow make and break contact mechanism to maintain tight differentials in critical applications such as steam tables, sterilizers, and water baths. With a calibrated temperature range of 60°F to 200°F (15°C to 93°C), it serves as a reliable control for low-to-medium heat equipment. The assembly features a 42-inch capillary and a 3/16" x 15-3/8" bulb, providing ample reach for remote sensing. Built to handle demanding electrical loads, it is rated for 20 Amps at 125V AC and 15 Amps at 250V AC. This SPST commercial thermostat is a primary replacement for Alto-Shaam TT-3057 and and other OEM heating controls, ensuring consistent switch action via high-grade fine silver contacts.

• Broad Compatibility: Fits a variety of commercial equipment including incubators, laboratory ovens, and dishwashers.
• Durable Construction: Features a nickel-plated copper bulb for enhanced corrosion resistance in wet environments like scalding tanks.
• Precision Control: Specifically designed for applications requiring a small temperature differential between make and break cycles.
• Flexible Installation: The 42-inch capillary length allows for versatile mounting positions away from the primary heat source.

Is the Robertshaw 5210-125 compatible with Alto-Shaam ovens?
Yes, this unit is a direct functional replacement for Alto-Shaam part number TT-3057 and Robertshaw factory part number Z87147.

What is the maximum amperage this thermostat can handle?
The switch is rated for 20 Amps at 125V AC and 15 Amps at 250V AC, making it suitable for high-draw commercial heating elements.

Can this be used in water immersion applications?
Yes, the zinc/nickel-plated bulb is designed for use in equipment such as water baths and steam tables, provided the capillary is protected from damage.
