Robertshaw 5300-623 Thermostat

As a veteran HVACR technician, you know that performance reliability is non-negotiable in commercial cooking and industrial heating applications. The Robertshaw 5300-623 Thermostat is a heavy-duty, snap-acting electric thermostat designed for precision temperature regulation between 100°F and 200°F. Engineered with single pole single throw (SPST) switch action, this open-high thermostat breaks the electrical circuit when the upper limit is reached, providing critical thermal protection for your equipment. Featuring a 5-foot capillary (60 inches) for flexible remote sensing, it facilitates easier installation in cramped control cabinets. The Robertshaw 5300-623 utilizes silver contacts and rugged terminals to ensure long-term electrical conductivity under high-demand 30 Amp loads. Whether you are performing a thermostat replacement in a commercial water heater, oven, or specialized heating system, this Robertshaw HVAC part offers the industrial-grade durability needed to minimize downtime and maintain consistent thermal cycles.

• Precise Temperature Range: Operates reliably between 100°F and 200°F (38°C to 93°C) for specific low-to-mid range heating applications.
• Extended 60-Inch Capillary: The 5-foot sensing tube allows for versatile bulb placement away from the primary control housing.
• High Electrical Rating: Capable of handling 30 Amps at 277V AC, making it suitable for demanding commercial equipment.
• Snap-Action Reliability: Features a high-quality snap-action mechanism with silver contacts to prevent arcing and ensure sustained accuracy.
• Complete Installation Kit: Typically includes a universal 4-way dial, bezel, and necessary mounting hardware for immediate field implementation.

• What does "Open-High" switch action mean for my installation? In this configuration, the thermostat contacts are normally closed and will "open" to break the circuit when the temperature rises to the setpoint, effectively cutting power to the heating element.
• Is the Robertshaw 5300-623 compatible with other brands? Yes, this unit is a common cross-reference for various OEM parts from manufacturers such as Bendix, Cornelius, Delfield, and GE Hill. Always verify your specific model's requirements.
• What is the mechanical differential for this model? Most 5300 series models within this range maintain a mechanical differential of approximately 5°F to 6°F, ensuring tight control over the heating cycle.
