The Robertshaw 5225-028 Limit Control is a factory-calibrated, non-adjustable safety device engineered for precision temperature protection in commercial cooking equipment and specialty HVACR applications. Specifically designed as an LCC Series auto reset limit, this control features a 450°F fixed temperature setting and a 36-inch nickel-plated copper capillary. As a veteran-grade high limit thermostat, it utilizes a negative biased power element diaphragm to ensure the circuit interrupts power immediately upon reaching the calibrated threshold. The SPDT switch action (Single Pole Double Throw) provides versatile wiring options, allowing for both a primary shutdown circuit and a secondary alarm signal. Built for reliability in high-ambient environments up to 185°F, this Robertshaw thermal limit switch is the standard for maintaining appliance safety limits in electric fryers and industrial heating tanks where automatic reset functionality is required for continuous operation after the temperature returns to a safe range. Extreme Durability: Features a rugged nickel-plated copper bulb and capillary for superior corrosion resistance in harsh commercial kitchen environments. Fail-Safe Design: Incorporates a hydraulic sensing element that automatically activates the controller if fluid loss occurs, preventing catastrophic overheat conditions. Versatile Compatibility: Commonly utilized as a direct replacement in Wolf Range (713803) and other major commercial appliance brands requiring a 450-degree commercial electric limit control. Automated Recovery: The LCC series eliminates the need for manual intervention by cycling the contacts back to the closed position once the temperature drops, maximizing equipment uptime. Common Questions What is the difference between this auto reset and a manual reset limit? The 5225-028 is an automatic reset limit control, meaning the contacts will re-close automatically once the temperature recedes below the 450°F set point. In contrast, manual reset models (LCH series) require a technician to physically depress a trip-free button to restore power, which is often preferred for electric fryer applications where an operator must acknowledge the fault. Can the 36-inch capillary be shortened? No. Never cut or kink the capillary tube. Bending or cutting the tube will release the hydraulic fluid, rendering the Robertshaw 5225 series inoperable. For proper limit control installation, coil any excess capillary away from heating elements and sharp edges. Is this control compatible with millivolt gas systems? The 5225-028 features an LCC-type switch rated for up to 480V AC. While typical for electric applications, if you are working with a gas system, ensure the electrical rating matches your solenoid or contactor load requirements. Always verify the limit control temperature range matches the original manufacturer specifications for the specific appliance. This item is not eligible for free shipping.
