Robertshaw 5300-023 Thermostat

The Robertshaw 5300-023 Commercial Thermostat is a heavy-duty, snap-acting electric thermostat designed for high-demand commercial cooking and industrial environments. This SPST (Single Pole Single Throw) control utilizes Direct Acting (D.A.) logic to maintain precise thermal regulation within a range of 175°F to 550°F. Built for durability, the unit features silver contacts and heavy-duty terminals to ensure sustained accuracy and reliable switching under heavy electrical loads. The 60-inch capillary tube provides extensive reach for versatile mounting, paired with a 3/16" x 11-5/8" nickel-plated sensing bulb for responsive temperature detection.

As a Robertshaw 5300 series component, this thermostat serves as a direct replacement for various OEM food service parts, including Vulcan Hart 411506-6 and Lang 30402-07. The Robertshaw 5300-023 is engineered with a 1/4" stem and includes a 4-way insert with an adjusting knob for straightforward mechanical calibration. Its rugged compact design and 12°F mechanical differential make it a standard choice for technicians maintaining commercial ovens, fryers, and griddles that require consistent, high-temperature performance.

• Broad Temperature Range: Operates from 175°F to 550°F, ideal for high-heat commercial kitchen applications.
• Precise Switching: Features a snap-action mechanism for fast, clean contact breaks that prolong component life.
• Extended Reach: The 60-inch capillary allows for flexible positioning of the sensing bulb in deep or complex equipment configurations.
• Cross-Brand Compatibility: Directly replaces Vulcan Hart 411506-6, Lang 30402-07, and Hobart 111506-6 units.
• Industrial Build: Equipped with silver contacts and a nickel-plated bulb to resist corrosion and wear in harsh environments.

Is this thermostat compatible with 277V systems?
Yes, the Robertshaw 5300 series is rated for up to 25 Amps at 250V-277V AC, making it suitable for standard commercial electrical configurations.

What does 'Direct Acting' mean for this model?
In direct acting thermostats, the contacts open on a rise in temperature, which is the standard operation for heating applications to prevent overheating.

Can I use this for a 120V application?
While often used in 240V/277V circuits, it is rated for AC voltage and can be used in 120V setups provided the amperage does not exceed the unit’s maximum rating.
