Ranco A30-X451 Control

The Ranco A30-X451 Control is a versatile, room air conditioner thermostat designed for high-performance temperature regulation in residential and light commercial cooling units. Built to handle 120/240V AC applications, this SPST (Single Pole Single Throw) cold control features an Open Low switch action, ensuring precise compressor cycling by opening the circuit when temperatures drop below the set point. With a temperature range of 58°F to 86°F and a fixed 5°F differential, this controller maintains tight environmental tolerances, making it an ideal field replacement for a variety of OEM refrigeration and thru-the-wall AC systems.

Engineered with a 36-inch capillary tube, the A30-X451 offers flexible routing to the evaporator coil or air stream for accurate sensing. As a vet in the field, you’ll appreciate the break-off shaft design, which allows you to customize the length to match existing dial configurations. The unit includes high-amperage contacts rated for up to 20A Full Load Amps (FLA), ensuring durability under heavy inductive loads. Whether you’re performing a quick service call or a complete system overhaul, this Ranco cold control delivers the HVACR technical specifications required for reliability in the field.

• Universal Compatibility: Includes a break-off shaft and mounting bracket to replace multiple OEM temperature controls.
• Precise Sensing: The 36" vapor-filled capillary allows for remote mounting and accurate feedback.
• Heavy-Duty Construction: Features laser-welded stainless steel bellows and 1/4" quick-connect terminals for secure electrical housing.
• Reliable Switching: Designed with high-amperage contacts to manage compressor on/off function without early contact pitting.

• Can I use this for heating applications? No, the Ranco A30-X451 has an Open Low action, meaning it breaks the circuit on temperature fall, which is specific to cooling and refrigeration cycles.
• How do I adjust the shaft length? The control is supplied with a "break-off" shaft featuring notches at various lengths; simply use pliers to snap it at the required depth for your specific knob or dial.
• What is the electrical rating? This unit is rated for 120/240V AC with a 20A Full Load and 80A Locked Rotor capacity at 120V.
