Robertshaw 5000-811 Thermostat

The Robertshaw 5000-811 is a high-performance commercial electric thermostat engineered for heavy-duty HVACR and cooking applications. Built for harsh industrial environments, this 5000 Series electric thermostat features a DPST (Double Pole Single Throw) snap-action mechanism that provides instantaneous switching and includes a positive OFF position for mechanical safety. With a temperature range of 60°F to 250°F (15°C to 121°C) and a highly sensitive 60-inch capillary, this unit ensures precise thermal regulation. The 3/8" x 4-1/2" sensing bulb is linked to a dual stainless steel diaphragm assembly, welded to provide maximum sensitivity and movement without fatigue. Rated for high-amperage loads, this Robertshaw 5000-811 thermostat handles up to 30 Amps at 120/277V AC, making it a reliable OEM replacement part for brands like Chromalox, General Electric, and Johnstone Supply. This Uni-Kit includes a 4-way dial, bezel, and pilot light for versatile mounting in various heater and oven configurations.

Key Benefits:

• DPST Snap-Action: Features an instantaneous, non-fatiguing switching mechanism with a positive mechanical OFF position.
• Extreme Sensitivity: Utilizing dual welded stainless steel diaphragms, the unit reacts to minute temperature changes for a narrow 6°F mechanical differential.
• Broad Compatibility: Directly replaces multiple OEM thermostats including Robertshaw 5000-210, 5020-003, and Johnstone F16-175.
• Flexible Installation: Equipped with a 60-inch copper capillary and a 3/8" diameter sensing bulb to accommodate complex commercial equipment layouts.
• Heavy-Duty Electrical Rating: Designed to switch loads up to 30 Amps at 277V AC, supporting high-wattage heating elements.

Common Questions:

What is the maximum electrical load for the Robertshaw 5000-811?
This thermostat is rated for 30 Amps at 120V and 277V AC, and 21 Amps at 480V AC.

Can I use this to replace a single-pole thermostat?
While this is a DPST (Double Pole) control, it can often replace single-pole units in commercial heating applications; however, you must verify the wiring schematic and amp draw to ensure it is suitable for the specific heater circuit.

Does the kit include the dial and bezel?
Yes, the 5000-811 is a Uni-Kit that includes the 60/250F 4-way dial, bezel, and a 220V pilot light for complete field installation.
