The Carrier HK680018 Control is a high-performance HVAC pressure switch designed for precision monitoring in commercial and industrial refrigeration systems. This OEM Carrier replacement part utilizes the Danfoss KPU6W platform, featuring a Single Pole Double Throw (SPDT) contact arrangement for versatile circuit control. Engineered to handle high-pressure applications, it operates within a robust regulation range of 100 to 600 psi, making it an essential component for system protection and fan cycling. The unit includes a 36-inch lead for streamlined integration into existing control panels and narrow-access housing.

Constructed with dual bellows, the Carrier HK680018 provides a fail-safe mechanism to prevent refrigerant loss. Its snap-action electrical contacts are specifically designed to minimize chatter and bounce, ensuring mechanical reliability under heavy vibration. As a high-pressure cutout switch, it automatically resets to maintain optimal discharge pressure, directly supporting the longevity of compressors and condenser fans in demanding environments.

• Precise Pressure Regulation: Tailored for high-side monitoring with a wide 100-600# adjustable range.
• SPDT Versatility: Dual-throw contacts allow for simultaneous control of multiple system functions or alarm circuits.
• Fail-Safe Design: Engineered with dual bellows to provide superior leak protection and system safety.
• Vibration Resistance: Rugged internal components prevent nuisance tripping in high-cycle HVACR applications.
• Factory Authorized Part: Ensures an exact drop-in replacement for specific Carrier, Bryant, and Payne equipment.

What is the reset function on the HK680018?
This model features an automatic reset function, ensuring the system resumes operation once pressure returns to the safe differential range.

Can this switch be used for both low and high pressure?
The HK680018 is specifically rated for high-pressure applications (up to 600 psi), typically used as a high-limit cutout or condenser fan cyclic control.

Is the 36" lead wire pre-installed?
Yes, the unit comes with a factory-integrated 36-inch electrical lead to simplify terminal connections in large-scale cabinets.
