Robertshaw 5300-219 Thermostat

The Robertshaw 5300-219 Thermostat is a heavy-duty, snap-acting electric cooking control designed specifically for the demanding environments of the commercial food service industry. This SPST (Single Pole Single Throw) thermostat operates with a precise temperature range of 60°F to 240°F, making it a critical component for medium-heat applications such as warming cabinets, commercial ovens, and specialty heating equipment. Featuring a 36-inch capillary and a high-accuracy 1/4" x 6.43" copper sensing bulb, this unit provides rapid thermal response to ensure consistent temperature regulation.

As part of the rugged Robertshaw 5300 series, the 5300-219 (cross-referenced as SP-390-36 or 2TY1668) utilizes silver-bonded contacts for superior electrical conductivity and durability under high-cycle conditions. The millivolt-compatible design includes heavy-duty terminals and a Type #1 mounting bracket with a 1-3/4" dimension for universal fitment in standard control panels. Mechanics will appreciate the 1/4 inch stem with the flat in the "down" position, ensuring immediate compatibility with standard pointer dials and knobs.

• Precise Thermal Control: Tight mechanical differential ensures stable process temperatures between 60°F and 240°F.
• Industrial Build Quality: Features silver contacts and a rugged snap-action mechanism for extended service life in commercial kitchens.
• Flexible Installation: Long 36-inch capillary length allows for versatile bulb placement away from the main control head.
• OEM Compatibility: Direct replacement for several commercial electric thermostats, simplifying field repairs for contractors.

Is the bulb compatible with corrosive environments?
The copper bulb is ideal for standard air and water applications; however, for highly acidic or caustic environments, technicians should verify if additional thermowell protection is required.

What is the electrical rating for this SPST switch?
This 5300 series model is typically rated for up to 30 Amps at 277V AC, providing sufficient overhead for most commercial resistive heating loads.

Can I use this to replace a different capillary length thermostat?
If the temperature range and bulb dimensions match, the 36-inch capillary can replace shorter leads, provided the excess tubing is coiled carefully to avoid kinking.
