TE Connectivity KHAU-17A11-24 Relay
The TE Connectivity KHAU-17A11-24 is a professional-grade 4PDT general purpose relay engineered for reliable performance in HVACR control circuits and industrial automation. Operating on a 24VAC coil, this 4-pole double-throw relay features a 2.5A contact rating, making it an ideal choice for low-power switching applications and signal isolation. The KHAU-17A11-24 relay is housed in a clear polycarbonate dust cover, protecting the internal switching mechanisms from environmental contaminants common in mechanical rooms. Designed for socket mount or solder terminal installation, it integrates seamlessly into existing general-purpose panels. Technicians often specify this plug-in relay when replacing Potter & Brumfield KHAU series components due to its proven thermal management and gold-flashed silver contacts that prevent oxidation in low-load applications. Whether you are troubleshooting a primary control loop or managing auxiliary fan sequencing, this 24V alternating current relay delivers the consistent mechanical life required for critical system uptime.
Key Benefits for Technicians- 4PDT Contact Configuration: Allows for simultaneous control of four independent circuits, streamlining complex wiring layouts.
- Solder/Plug-In Terminals: Provides flexible installation options for both fixed wiring and rapid-swap socket applications.
- Compact Enclosure: The polycarbonate housing offers visual inspection of contact status while maintaining a small footprint in crowded electrical cabinets.
- 24VAC Coil Compatibility: Standardized for most 24-volt HVAC transformer outputs and industrial control transformers.
What is the maximum current rating for the KHAU-17A11-24?
This relay is rated for 2.5 Amps at 240VAC or 28VDC, specifically designed for pilot duty and low-current signal switching rather than heavy motor loads.
Can I use this relay to replace other KH-style relays?
Yes, as long as the coil voltage is 24VAC and the contact arrangement matches the 4PDT specifications. Always verify the pin configuration (solder vs. PCB) for your specific socket.
How do I verify if the coil is energized?
The clear polycarbonate cover allows for direct visual confirmation of the armature position, though a multimeter should still be used at the coil terminals to verify supply voltage.
