Ranco O10-1401 Control

When you're out in the field and need a reliable low pressure cut-out to protect a compressor from loss of refrigerant, the Ranco O10-1401 is a standard choice for refrigeration and HVAC technicians. This single function pressure control is engineered with a SPST switch that opens on pressure fall, providing critical low limit protection for both residential and commercial applications. With an auto reset feature and a versatile range from 12" Hg to 50 PSI, this unit offers the flexibility required for various refrigeration cycles. The inclusion of the Super Cap capillary protection system and a low mass copper alloy capillary tube significantly reduces failure points caused by equipment vibration, ensuring the Ranco O series remains stable under demanding conditions. Its NEMA 1 enclosure and easy-to-read scale plate make it a straightforward HVAC pressure switch replacement for contractors looking for a universal mounting solution with 1/4" SAE male flare connections.

• Universal Compatibility: Works with most common refrigerants, including R-22, R-134A, and R-404A, making it a versatile addition to any service truck.
• Built for Durability: Features laser-welded bellows and a heavy-duty plated steel frame for extended service life in high-vibration environments.
• Ease of Installation: The compact design and front-located captive cover screw allow for quick wiring and mounting in tight control cabinets.
• Precise Control: Adjustable differential from 5 to 35 PSI enables fine-tuning to prevent short-cycling and protect the compressor effectively.

Is the Ranco O10-1401 suitable for high-pressure applications?
No, this model is specifically a low pressure control. If you need a high-pressure cut-out, you should look for the Ranco O12 or O16 series designed for high-side limits.

What does 'Open Low' mean for this switch?
'Open on Fall' or 'Open Low' means the SPST contacts will break the circuit when the pressure drops to your set point, stopping the compressor to prevent damage from a vacuum or low charge.

Does this unit require a manual reset?
This specific model features an automatic reset, meaning the system will restart once the pressure rises back above the differential set point.
