Robertshaw 5225-044 Thermostat

The Robertshaw 5225-044 is a heavy-duty manual reset limit control engineered for critical temperature protection in commercial cooking equipment, specifically high-output fryers and ovens. Part of the Robertshaw LCH series, this non-adjustable safety thermostat features a fixed 450°F trip point, ensuring positive power interruption the moment internal temperatures exceed safe operating parameters. The 30-inch copper capillary and 1/4" x 4-7/8" nickel-plated bulb provide precise thermal response, making it a drop-in replacement for Vulcan Hart 110705-2, Ultra Fryer, and Hobart commercial appliances.

Designed with a single pole single throw (SPST) switch mechanism that breaks on temperature rise, the 5225-044 utilizes a negative biased power element diaphragm. This "safe-off" design ensures that if the capillary loses pressure or integrity, the control will automatically lock in the open position to prevent equipment damage. It is an essential component for technicians maintaining commercial fryer high limit safety standards and is factory-calibrated for long-term reliability in high-ambient kitchen environments.

• Factory Calibrated: Pre-set at 450°F (232°C) to ensure precise safety cut-off without the need for field adjustment.
• Manual Reset Safety: Features a trip-free manual reset button that prevents the appliance from restarting until the operator acknowledges the over-temperature condition.
• Cross-Brand Compatibility: Fits major OEM equipment including Vulcan Hart, Ultra Fryer, and APW systems.
• Durable Construction: Nickel-plated copper bulb and 30" capillary resist corrosion and withstand the rigors of commercial oil and steam.
• Safe-Failure Mode: The negative biased diaphragm ensures the circuit opens if the thermal element is compromised.

• Can this control be used for automatic cycling? No, the 5225-044 is a safety high-limit control designed for manual reset only. It should not be used as a primary temperature controller.
• What brands does this replace? It is a direct replacement for Vulcan Hart 410705-2, Ultra Fryer 22543, and several APW models.
• What happens if the capillary breaks? The unit is designed to fail-safe; if the capillary leaks, the switch will open and prevent the unit from heating.
