FAQs
The HCU2235D6IP31 is engineered for floor-mounted installation in 600 V three-phase networks and supports 50/60 Hz operation. It integrates with existing switchgear and feeders through compatible busbars and mounting hardware, enabling straightforward retrofits or new builds without major reconfiguration.
This unit complies with IEC 61000-3-2 and IEC 61000-3-4, IEEE Std. 519, UL 508C, and CSA Std. C22.2 No. 14, providing broad regulatory alignment for commercial and industrial environments and facilitating procurement for regulated projects.
IP31 indicates indoor protection against solid objects and incidental contact. Plan for a level floor space, access clearances for maintenance, and appropriate ventilation. The unit’s footprint (61.12 in L, 88.32 in H, 29.62 in W) requires dedicated floor area and structural support.
Facilities with high non-linear loads—such as drives, CNCs, presses, and large motor systems—benefit from reduced harmonic distortion, improved power factor, and more stable voltage profiles, aiding compliance and lifecycle performance.
Benefits include reduced thermal stress, fewer harmonic-related outages, and enhanced reliability, contributing to lower maintenance costs and energy budgets. ROI depends on harmonic profile, load mix, and existing compliance gaps, but standardized mitigation often shows faster payback in high-load facilities.
