Electric thermostat for commercial HVAC
The Robertshaw 5300-641 is a capillary-tube thermostat rated for 120/277 VAC service with a 450 °F maximum temperature setting. It suits technicians maintaining ovens, fryers or other high-temperature equipment that requires direct bulb sensing rather than electronic control.
Stable control across the full range
The 36-inch capillary and 7 1/2-inch sensing bulb deliver consistent response during extended heating cycles, avoiding the short-term overshoot common with shorter capillaries. A 2-inch stem length provides standard engagement for typical mounting brackets in commercial cooking appliances.
Direct replacement for multiple brands
The bulb diameter of 3/8 inch and stem dimensions match original Devco, Johnstone Supply, Robertshaw and Uni-Line units, so retrofit installations proceed without adapter fittings. No restricted-state limitations apply, allowing deployment across all service territories.

Questions about this item
How much heat does the Robertshaw 5300-641 generate during continuous operation?
The thermostat is a mechanical control device and does not generate measurable heat; it simply opens or closes the circuit based on the capillary temperature.
What voltage supply must already be present for the 5300-641 to function?
A 120 VAC or 277 VAC supply is required; the thermostat is rated for both voltages.
Will the 36-inch capillary fit the same mounting points as my older 5300 series thermostat?
Yes, the 36 in capillary and 3/8 in sensing bulb match the standard 5300 series dimensions for direct replacement.
