Robertshaw 5225-069 Limit Control

The Robertshaw 5225-069 is a heavy-duty manual reset limit control designed for high-temperature commercial cooking equipment and industrial HVAC applications. This high-limit safety switch features a 600°F (315°C) fixed temperature setting and a 60-inch copper capillary, providing the reach necessary for remote mounting in deep fryers, ovens, and griddles. As an LCH Series limit control, it utilizes a DPST (Double Pole Single Throw) switch configuration typically rated at 25 Amps, 250V AC, ensuring it can handle the electrical load of most commercial heating elements. The bulb is meticulously calibrated to interrupt the circuit if the primary thermostat fails, preventing oil flash fires or structural damage to the appliance. When diagnosing a commercial fryer limit switch failure, the 5225-069 offers a robust replacement for OEM parts, maintaining high-temperature safety standards and preventing nuisance tripping under normal operating conditions. Contractors rely on this Robertshaw thermal limit for its precise mechanical action and durable capillary tubing.

• Thermal Limit Trip Point: Fixed at 600°F (315°C) for critical overheat protection.
• Capillary Length: 60-inch copper lead allows for versatile sensor placement away from the control panel.
• Switch Configuration: DPST (Double Pole Single Throw) manual reset design prevents automatic restarts until investigated.
• High Ampacity: Rated for up to 25 Amps at 250V AC, suitable for demanding commercial kitchen equipment.
• Bulb Dimensions: 3/16" x 4-3/4" nickel-plated copper bulb for rapid thermal response and corrosion resistance.
• OEM Compatibility: Replaces numerous OEM part numbers in fryers such as Frymaster, Hobart, and Vulcan.

Why is my Robertshaw 5225-069 tripping frequently?
Frequent tripping usually indicates a failure of the primary temperature controller causing an overshoot, or a build-up of scale/sediment around the sensing bulb preventing accurate heat dissipation. Verify the operating thermostat's calibration before replacing the limit switch.

Can the capillary be shortened or bent?
The capillary contains a pressurized fluid; it must never be cut or crimped. Do not bend the tubing within 1/2 inch of the bulb or the control head, as this can lead to mechanical failure or inaccurate temperature sensing.

Is this limit control suitable for steam applications?
This specific model is calibrated for 600°F, which is far above steam boiling points. For steam or low-temp water applications, a limit control with a lower set point should be selected to ensure safety.
