Robertshaw 5300-043 Thermostat

The Robertshaw 5300-043 Thermostat is a professional-grade, snap-acting electric cooking control engineered for precision in commercial food service applications. This SPST (Single Pole Single Throw) direct-acting thermostat features a temperature range of 60°F to 250°F (16°C to 121°C), making it ideal for warming cabinets, proofers, and low-temp ovens. Built with a 48-inch capillary and a nickel-plated bulb, this unit ensures high corrosion resistance and reliable thermal conductivity in demanding kitchen environments. The 5300 Series is designed for durability, utilizing heavy-duty terminals and silver contacts to maintain accuracy over thousands of cycles. For technicians performing a direct replacement, the 3/16-inch stem length and standard 1-3/4-inch mounting facilitate a clean swap-out with minimal downtime. Its mechanical differential of 8°F provides a stable thermal response, preventing short-cycling while maintaining consistent cabinet temperatures.

• Broad Operating Range: Adjustable control from 60°F to 250°F covers a wide variety of commercial warming and proofing requirements.
• High Corrosion Resistance: The nickel-plated bulb and capillary stand up to humidity and chemical exposure in busy kitchen lines.
• Reliable Snap-Action: Features a high-quality Robertshaw 5300 series snap-action mechanism for crisp electrical breaks and long contact life.
• Flexible Mounting: Equipped with a 4-way dial type and standard mounting dimensions for versatile HVACR equipment parts integration.

Can I use this to replace a copper-bulb thermostat?
Yes, as long as the temperature range and electrical ratings match. The nickel plating on the 5300-043 offers superior protection against oxidation compared to standard copper.

Does the 48-inch capillary limit mounting options?
The 4-foot length provides sufficient reach for most cabinet configurations, but avoid sharp kinks or bends in the capillary tube during installation to ensure accurate sensing.

Is this compatible with millivolt systems?
No, the Robertshaw 5300-043 is an electric thermostat designed for line voltage applications. For millivolt systems, you must specify an RX series model with hermetically sealed reed switches.
