Robertshaw 5300-613 Thermostat

When you are in the field servicing commercial kitchen rigs, you need a control that handles heavy-duty electrical loads without flinching. The Robertshaw 5300-613 is a professional-grade, direct-acting electric thermostat designed for high-performance temperature regulation in commercial ovens, ranges, and warming cabinets. This SPST snap-acting thermostat provides a clean "break on rise" operation with a precise mechanical differential of approximately 8°F, ensuring stable heat cycles that prevent cabinet temperature swings.

Engineered with a 60-inch capillary tube and a 5/16" x 6-1/8" copper sensing bulb, this 5300 Series Uni-Kit (replaces SP-185-60) offers maximum installation flexibility for deep-cavity equipment. The Robertshaw 5300-613 thermostat is rated for up to 30 Amps at 277V AC, making it a rugged choice for commercial cooking equipment repair. Its silver-contact construction and heavy-duty terminals are built to withstand the high-ambient conditions of a busy galley, while the 60°F to 250°F range provides the narrow-band control required for precise food holding and proofing applications.

• Direct Acting SPST Switch: Reliable snap-action mechanism ensures a crisp electrical break to prevent arcing and sustain long-term contact integrity.
• Broad Compatibility: Cross-references with major brands including Cutler Hammer, Johnstone Supply, and Wells commercial units.
• High Amperage Rating: Rated for 30A @ 277V AC and 20A @ 480V AC, suitable for high-wattage resistive heating elements.
• Flexible Installation: Features a 2-inch stem and includes various dial adapters for 4-way mounting versatility in the field.

What does 'Open-High' or 'Direct Acting' mean for this model?
In the context of the 5300-613, direct acting means the switch contacts are normally closed and will snap open (break the circuit) when the sensing bulb reaches the high-temperature setpoint.

Can I use this to replace a millivolt system thermostat?
No, this is a high-voltage AC control. For millivolt applications, you must use the Robertshaw RX series which features hermetically sealed reed switches compatible with low-voltage pilots.

How do I handle the 60-inch capillary during installation?
Never kink the capillary. Use a 1/2" minimum bend radius and ensure the bulb is securely mounted in the path of the medium being measured for the most accurate thermal response.
