FAQ

Q1: What is a UL-certified AC contactor?

A UL-certified AC contactor meets the Underwriters Laboratories (UL) safety standards, ensuring reliable operation, electrical insulation, and fire resistance suitable for U.S. and global HVAC systems.

Q2: What’s the difference between 2P and 3P contactors?

A 2P (two-pole) contactor controls single-phase circuits, while a 3P (three-pole) contactor is used in three-phase systems such as HVAC compressors or heat pumps.

Q3: What coil voltage should I choose?

24V AC for low-voltage control systems (common in residential HVAC).
220V AC for industrial or direct line-voltage control circuits.

Q4: Can KAK contactors be used for compressor applications?

Yes. KAK AC contactors are designed for compressors, fan motors, and refrigeration circuits, providing stable operation under frequent switching.

Q5: Does KAK support OEM labeling?

Yes. OEM/ODM service is available for labeling, packaging, and technical customization upon request.
