Ranco A12-1506 Control

The Ranco A12-1506 Cold Control is a veteran-grade constant cut-in temperature control engineered specifically for refrigeration systems requiring reliable off-cycle defrost. This SPST close-on-rise switch is a direct one-for-one replacement for vending machines, reach-in coolers, and beverage dispensers. The unit features a fixed 38°F cut-in temperature, ensuring the evaporator is cleared of frost before the compressor restarts. With a 39-inch capillary tube and a 3/8" x 1-3/8" sensing bulb, it offers versatile placement for accurate thermal feedback.

Designed for industrial-strength performance, the A12-1506 refrigeration control utilizes laser-welded stainless steel bellows and high-amperage contacts rated at 16 FLA and 80 LRA at 120/240 VAC. The wide 9°F to 22°F temperature range and pneumatic action vapor-filled capillary provide the precision response techicians demand in high-duty cycle environments. For fast field installation, the control includes standard 1/4-inch quick-connect terminals and a break-off shaft for universal fitment across various A12 series applications.

• Constant Cut-In Precision: Fixed 38°F cut-in ensures consistent defrost cycles, preventing evaporator freeze-ups in high-humidity applications.
• Heavy-Duty Electrical Rating: 16 Amp full load capacity handles standard refrigeration compressors without the need for additional contactors.
• Durable Sensing Element: The 39-inch vapor-filled capillary provides fast response times and resists vibration fatigue in commercial units.
• Universal Mounting: Includes a flatted break-off shaft and standard mounting brackets for seamless replacement of OEM Robertshaw or Ranco controls.

What is the primary function of the constant cut-in feature?
It provides an automatic off-cycle defrost. The contacts stay open until the bulb senses the 38°F cut-in point, guaranteeing that any frost accumulation on the evaporator has melted before the cooling cycle resumes.

Can this control replace an adjustable differential thermostat?
The Ranco A12-1506 is a constant cut-in control, meaning the cut-in temperature is fixed at 38°F while the cut-out point (Cold Off/Warm Off) is adjustable between 9°F and 22°F. Ensure your application requires a fixed defrost point before installation.

What are the electrical terminal specifications?
This unit uses standard 1/4" quick-connect terminals, facilitating a direct swap for most commercial reach-in and vending machine wiring harnesses.
