Ranco A30-263 Refrigeration Control

The Ranco A30-263 provides specialized constant differential temperature control for various high-pressure refrigeration systems. This SPST cold control is engineered with a wide temperature range of 15°F to 40°F, making it a reliable solution for maintaining evaporator temperatures in a range of light commercial applications. Featuring an 84-inch capillary tube, this control allows for versatile bulb placement, ensuring accurate sensing even in remote configurations. For the service technician, the A30-263 refrigeration control offers a cut-out adjustment to dial in precise thermal cycles, while the 20-amp, 120/240V rating handles inductive loads typical in field replacements. Whether you are performing HVACR troubleshooting or a standard preventative maintenance swap, this direct-acting control ensures consistent compressor cycles and prevents coil freeze-ups in various commercial refrigeration parts layouts. The toggle-type action provide snap-action switching, significantly reducing contact arcing and extending component longevity in high-demand environments.

Key Benefits

• Broad Temperature Range: Maintains a 15°F to 40°F range with a 5°F constant differential for stable system cycles.
• Extended Capillary Reach: The 84-inch capillary length facilitates installation in large reach-in units and remote evaporator coils.
• High Amperage Rating: Reliable 20 Full Load Amps (FLA) capacity at 120/240V suits most single-phase compressor circuits.
• Universal Mounting Compatibility: Standard bracket design allows for a seamless replacement process for older Ranco A30 series controls.
• Single Pole Single Throw (SPST): Direct action simplifies wiring configurations during refrigeration repair.

Common Questions

What is the fixed differential on the Ranco A30-263?
This control features a 5°F constant differential, meaning the difference between the cut-off and cut-in points remains fixed regardless of the range adjustment.

Can the A30-263 control be used for walk-in coolers?
Yes, provided the temperature range of 15°F to 40°F matches your specific setpoint requirements, particularly for evaporator coil sensing.

Does this unit include the adjustment knob?
Yes, the A30-263 typically comes with a standard adjustment knob and mounting hardware for immediate field installation.
