FAQs
HCUN050Y4N1 is designed for wall-mount indoor use with UL Type 1 protection. When retrofitting, ensure adequate front clearance for service access, proper panel mounting surfaces, and compatibility with 208-415 Vac three-phase feeders. Verify feeder protection sizing and ensure panel space accommodates the device height and wiring routes to maintain safe installation clearances.
An active harmonic correction unit detects harmonic content in the supply current and injects counter-active harmonics to cancel distortion, improving power factor and reducing current peak demands. For HCUN050Y4N1, the 50A, 208-415 Vac, three-phase configuration enables effective correction in mid-to-large scale industrial loads while maintaining stable voltage regulation.
Yes. HCUN050Y4N1 targets three-phase power quality, making it well suited for data centers and motor-drive-intensive environments. By reducing harmonic currents, it lowers cooling requirements, enhances efficiency, and extends equipment life, which is particularly valuable where uptime and reliability are critical.
HCUN050Y4N1 is specified with UL Type 1 enclosure protection for indoor wall-mount installations. In global deployments, CE marking may be considered where required by regional regulations. Always verify site-specific electrical codes and enclosure requirements to ensure full compliance for your installation.
The unit delivers measurable ROI through improved power quality, lower energy waste, and reduced heat in downstream equipment, translating to energy savings and longer life for motors and drives. Maintenance primarily involves periodic inspections and wiring integrity checks; follow Eaton’s datasheet guidance to maintain performance and reliability.
