Ranco A12-1560 Temperature Control

The Ranco A12-1560 Temperature Control is a professional-grade constant cut-in cold control engineered for medium-temperature commercial refrigeration applications. Designed as a direct replacement for Robertshaw 3030-410 and K12-L-1560-001, this SPST cold control ensures precise off-cycle defrost by maintaining a fixed 38°F cut-in temperature. This functionality prevents frost accumulation on the evaporator by ensuring the coil temperature rises above freezing before the compressor restarts, regardless of the dial setting. Equipped with a 72-inch capillary tube for flexible sensing placement, the A12-1560 is a standard component for commercial refrigeration repair in vending machines, beverage dispensers, and reach-in coolers. The laser-welded stainless steel bellows and high-amperage contacts (16 FLA at 120/240V) provide reliable switching for heavy-duty HVACR refrigeration parts in demanding environments. Technicians can adjust the cut-out range between 19°F and 29°F to fine-tune system performance while preserving the essential defrost cycle.

• Universal Compatibility: Serves as a direct replacement for 3030-410, simplifying field substitutions in various commercial housings.
• Automated Defrost Logic: The constant cut-in 38F design allows the evaporator to clear frost during every off-cycle for peak cooling efficiency.
• Heavy-Duty Electrical Specs: Rated for up to 16 full-load amps and 80 locked-rotor amps at 120/208/240V AC.
• Precision Sensing: Features a 72" capillary for accurate remote temperature monitoring away from the control body.
• Simplified Installation: Includes a standard SPST break-on-temperature-drop switch with an "OFF" position for manual system shutdown.

Common Questions

Is the A12-1560 compatible with my reach-in cooler?
This control is designed specifically for reach-in coolers and vending equipment requiring a fixed 38°F cut-in. If your original part is a Robertshaw 3030-410 or another A12-series constant cut-in control, this is the correct technical specification.

How do I adjust the temperature settings on this control?
Rotating the adjustment dial changes the cut-out temperature (when the compressor stops), typically between 19°F (Cold Off) and 29°F (Warm Off). The 38°F cut-in (when the compressor starts) remains constant to ensure the defrost cycle is completed.

What is the purpose of the constant cut-in feature?
It ensures an off-cycle defrost. By waiting until the sensing point hits 38°F before restarting, it guarantees that any ice formed on the evaporator has melted, maintaining proper airflow and heat transfer.
