Ranco O10-1483 Control

The Ranco O10-1483 is a heavy-duty single pole single throw (SPST) pressure control engineered for high-pressure cutout applications in commercial refrigeration and air conditioning systems. This open-on-low pressure switch features an adjustable range of 10 to 100 PSI, providing critical protection against low refrigerant levels or loss of charge that can lead to compressor failure. Equipped with a 36-inch capillary tube and a 1/4 inch flare nut, this low pressure cutout switch allows for flexible mounting within tight mechanical cabinets. The Ranco O series control is built with a rugged NEMA 1 enclosure and high-grade bellows to ensure precise HVAC pressure regulation under demanding cycling conditions. Contractors rely on this universal pressure control for its repeatable trip points and durable internal snap-action switches, making it a standard refrigeration pressure switch replacement for systems requiring reliable circuit interruption on pressure drops.

Key Benefits

• Adjustable Range: Provides a versatile 10 to 100 PSI operating window with a fixed 20 PSI differential for precise system calibration.
• Flexible Installation: The 36-inch capillary length accommodates remote sensing locations away from severe vibration zones.
• Durable Construction: Features a high-quality SPST switch mechanism designed for high-cycle industrial applications.
• Universal Compatibility: Compatible with most non-corrosive refrigerants, making it a versatile truck-stock item for service calls.

Common Questions

What is the electrical rating for the Ranco O10-1483?
This control is rated for heavy-duty pilot duty and motor loads, typically handling up to 24 FLA and 144 LRA at 120V AC, or 16 FLA and 96 LRA at 240V AC.

Can this control be used for high-pressure safety cutout?
No, the O10-1483 is an "Open Low" control designed to break the circuit when pressure drops below the set point. For high-pressure safety, an "Open High" model (O10-1402 or similar) is required.

Does this unit feature a manual reset?
This specific model is an automatic reset control. Once the pressure rises above the differential setting, the SPST switch will automatically close to resume operation.
