Robertshaw 5225-207 Limit Control

The Robertshaw 5225-207 is a mission-critical high-limit control designed for precise temperature protection in commercial HVACR and cooking equipment. Engineered for rigorous use, this 425F limit switch features a 36-inch capillary and a nickel-plated copper bulb (5/16" x 3-5/8"), providing rapid thermal response times to interrupt power if temperatures exceed factory-calibrated thresholds. As a 5225 series LCC automatic reset control, it utilizes a negative biased power element diaphragm and SPDT switch action, allowing for both circuit interruption and the integration of an auxiliary alarm system. For contractors servicing commercial fryer high limits or industrial heating units, the Robertshaw 5225-207 auto reset ensures operational safety without the need for manual intervention once the system cools approximately 25°F below the trip point. This HVAC high-limit switch replacement is built for durability, featuring a robust #7 mounting bracket and a 1/4" stuffing box for secure installation in high-demand environments.

Key Benefits

• High-Temperature Calibration: Factory-set at 425°F (218°C) for reliable protection against overheating in commercial appliances.
• Automatic Reset Mechanism: Eliminates downtime by automatically restoring the circuit once temperatures fall safely below the limit.
• Durable Sensing Element: 36-inch Robertshaw capillary tube with nickel-plated construction resists corrosion in harsh kitchen or industrial environments.
• Versatile SPDT Switching: Equipped with Single Pole Double Throw (SPDT) action to shut down the heating load while simultaneously triggering a status alarm.
• Broad Compatibility: Cross-references with industry-standard parts from Lang, Johnstone Supply, and Dean for streamlined inventory management.

Common Questions

Does this unit require a manual reset button to restore power? No, the Robertshaw 5225-207 is an automatic reset model. It will cycle back to the closed position on its own once the sensed temperature drops roughly 25-50 degrees below the 425°F trip point.

Can this limit control be used in both gas and electric fryer applications? Yes, it is compatible with various configurations. Because it is an LCC series control with SPDT action, it is frequently used to interrupt power to the solenoid coil in gas systems or the contactor circuit in electric equipment.

What happens if the capillary tube is kinked or the fluid is lost? This control is designed with a negative biased power element. If the hydraulic fluid in the capillary is lost due to damage or a leak, the switch will react as if an over-temperature condition has occurred and open the circuit for safety.
