TE Connectivity KHAU-17A12-120 Relay
The TE Connectivity KHAU-17A12-120 Relay is a specialized 4PDT general purpose relay designed for high-density switching in HVACR control circuits and industrial automation. Operating on a 120VAC coil voltage, this 4 Form C relay is engineered for technicians who require reliable performance in panel mount or socket mount configurations. The unit features solder terminals for secure, vibration-resistant terminations, essential for high-duty cycle applications. With a 5A contact current rating at 240VAC and silver cadmium oxide contacts, it provides superior arc resistance and conductivity. The clear polycarbonate dust cover facilitates easy visual inspection of the mechanical operation, while the UL Class B insulation ensures thermal stability across an operating temperature range of -45°C to 70°C. This Cradle relay is an industry standard for multi-pole switching where space and reliability are critical factors.
Key Technician Benefits
- Broad Compatibility: Direct replacement for many 4-pole plug-in relays used in commercial air handlers and process controllers.
- Enhanced Durability: Silver cadmium oxide (AgCdO) contacts offer higher resistance to welding compared to standard silver contacts.
- Environmental Protection: The dust-protected enclosure prevents particulate contamination of the switching mechanisms in mechanical rooms.
- Application Versatility: Supporting both solder and plug-in termination, it integrates seamlessly into existing wiring harnesses or DIN-rail sockets.
- High Dielectric Strength: Rated at 1500 Vrms between coil and contacts, providing essential circuit isolation.
Common Questions
What are the primary applications for the KHAU-17A12-120?
This 120V AC relay is typically used for sequencing multiple loads, interlocking controls, and signal duplication in industrial control systems and HVAC logic boards.
Can this relay be used with a standard socket?
Yes, while it features solder terminals, it is fully compatible with standard KHA series sockets for quick field replacement and reduced downtime.
What is the maximum switching capacity?
The contacts are rated for a 5 Amp general purpose load at 240VAC, making it suitable for pilot duty and small fractional horsepower motor control.
