Robertshaw 5300-088 Thermostat

The Robertshaw 5300-088 Thermostat (KA-601) is a heavy-duty commercial electric thermostat engineered for precise temperature regulation in high-demand environments. This Robertshaw 5300 series control features a snap-acting SPST mechanism designed to open on temperature rise, making it an essential component for commercial ovens, fryers, and grills. With a wide operational range of 100°F to 550°F and a 72-inch capillary, this unit provides the flexibility needed for various equipment configurations. The integrated auxiliary switch provides a mechanical "positive off" feature when the dial is rotated to the off position, ensuring total circuit interruption for safety and maintenance. Built to handle inductive loads up to 13A and resistive loads up to 25A at 250V AC, this high-temperature control is a rugged solution for technicians requiring OEM quality HVACR parts for industrial cooking applications.

Key Benefits for Contractors

• Broad Compatibility: Replaces multiple 5300 series models and works as a universal heating control for various commercial kitchen brands.
• Durable Construction: Features a nickel-plated bulb (1/4" x 5-9/16") to resist corrosion in harsh kitchen environments.
• Precise Calibration: Maintains a 14°F mechanical differential for consistent thermal cycling and energy efficiency.
• Simplified Installation: Includes a #6 mounting kit and 4-way dial (1-10 scale) for fast field replacement.
• Enhanced Safety: The auxiliary switch uni-kit design adds an extra layer of mechanical disconnect not found on standard cycling thermostats.

Common Questions

Is the Robertshaw 5300-088 compatible with pilot duty circuits?
Yes, this model is rated for pilot duty at 125VA at 120/277V AC, making it suitable for both power and control circuit applications.

Can I use this to replace a thermostat with a shorter capillary?
Yes, the 72-inch capillary provides extra length for complex routing; however, ensure any excess tubing is coiled away from high-heat zones and electrical terminals to prevent interference.

What does 'Open High' signify in this context?
'Open High' refers to the SPST switch logic where the electrical contacts open—breaking the circuit and stopping the heat—once the temperature reaches the set point on the dial.
