FAQs
HCUN020Y4N1 is designed for indoor, wall-mounted installations in three-phase electrical systems typical of manufacturing floors, data centers, and HVAC applications. It handles up to 20 A at 208-415 Vac, providing effective harmonic correction in compact control spaces. Ensure adequate clearance for service access and cooling within UL Type 1 compliant enclosures.
The unit actively corrects harmonic currents by injecting compensating signals, lowering total harmonic distortion (THD) and improving power factor. This reduces heat generation, minimizes equipment wear, and decreases nuisance trips. In practice, users experience more stable motor operation, enhanced system efficiency, and reduced maintenance needs across automation and processing lines.
Yes. HCUN020Y4N1 is designed for indoor wall-mount use with UL Type 1 enclosure protection. Installation considerations include ensuring sufficient space around the cabinet for ventilation and service access. The system is configured for three-phase plus neutral operation at 208-415 Vac, supporting typical industrial power distribution layouts.
Model HCUN020Y4N1 supports 20 A with a voltage rating of 208-415 Vac in a three-phase plus neutral configuration. It is a wall-mounted harmonic correction unit within the Harmonic Correction Units category, weighing 280 lb, with dimensions approximately 69.5 in wide, 28 in high, and 29 in deep.
