Robertshaw 5300-500 Thermostat

The Robertshaw 5300-500 is a heavy-duty high-limit thermostat engineered for precise temperature control in demanding commercial cooking and heating applications. Operating within a 300°F to 700°F temperature range, this SPST (Single Pole Single Throw) switch is designed to break the circuit upon temperature rise, providing essential over-temperature protection. This specific model features a 36-inch tin-zinc capillary, offering the durability and flexibility required for deep-seated probes in commercial fryers and ovens. As a direct replacement for SJ170-36, it ensures seamless mechanical compatibility for contractors performing field service. The 5300 series is recognized for its manual reset functionality and reliable snap-action switch mechanism, which prevents arcing and ensures consistent performance under high-amp loads. For technicians seeking a 300/700F 36" capillary high limit, this component provides the exact thermal response curve needed to maintain equipment safety standards and operational uptime.

• Broad Thermal Range: Calibrated for high-heat environments between 300°F and 700°F.
• OEM Compatibility: Precision drop-in replacement for SJ170-36 eliminates the need for bracket modification.
• Durable Capillary: The 36-inch tin-zinc plated tubing resists corrosion and mechanical fatigue in high-vibration commercial kitchens.
• Snap-Action Reliability: High-amperage rated contacts ensure a crisp break in electrical continuity when limits are exceeded.
• Compact Design: Standard 5300 series footprint fits most commercial control panels and mounting configurations.

Is the 5300-500 a manual or automatic reset?
This model is a manual reset high-limit, meaning once the temperature exceeds the 700°F threshold, the operator must manually depress the reset button after the temperature has cooled sufficiently.

Can this replace a shorter capillary version?
While the 36-inch capillary provides extra reach, it is critical to secure any excess tubing away from heating elements to prevent false readings or mechanical damage.

What is the electrical rating for this Robertshaw thermostat?
The 5300 series typically handles high-wattage loads common in commercial appliances; however, always verify the specific amperage requirements of your equipment against the switch rating before installation.
