This 5300 Series electric control features a single pole single throw (SPST) snap-acting switch, ensuring rapid and reliable response times to maintain consistent thermal environments. With a broad temperature range of 175°F to 550°F and a 72-inch capillary, this unit provides the flexibility needed for proper sensing bulb placement in diverse equipment configurations. The Robertshaw 5300-040 thermostat utilizes silver contacts and rugged terminals to sustain accuracy under the demanding conditions of a commercial kitchen. It is frequently employed as a replacement thermostat for commercial ovens and fryers, offering a direct-acting mechanism that prevents temperature overshoot. For technicians performing a Robertshaw 5300-040 installation, the 1/4" D-stem provides easy dial integration. This unit is built to withstand high ambient temperatures up to 200°F at the control body, making it a staple for equipment from manufacturers like American Range, Anets, and Pitco.

• Broad Operating Range: Covers 175°F to 550°F, making it suitable for baking, roasting, and high-heat frying applications.
• Extended Reach: The 72-inch capillary tube allows for versatile mounting away from the heat source.
• Snap-Acting Reliability: Precision SPST switch mechanism reduces arcing and enhances contact life.
• Industry Standard Compatibility: Serves as a universal electric cooking control for multiple commercial brands.

What equipment is compatible with the Robertshaw 5300-040?
This control is typically used in commercial ovens, ranges, and deep fryers from brands such as Southbend, Imperial, and Frymaster where a high-limit or primary temperature control is required.

Can the capillary tube be shortened if it is too long?
No, never cut or kink the capillary. The tube contains a fluid that expands to activate the diaphragm; breaking the seal will render the thermostat inoperable.

Is this a millivolt or line voltage thermostat?
The 5300-040 is an electric thermostat rated for 120/277V AC applications, commonly used in 25 Amp resistive load circuits.
