FAQs
The HCU2235D6N12 is designed for floor mounting in NEMA 12 environments, with top or bottom cable-entry options for flexible routing. It includes an integral disconnect for safe servicing and easy alignment with lockout/tagout procedures. Ensure sufficient floor space for access, clearance for cable connections, and compatibility with 600 V three-phase systems. This minimizes retrofit challenges and accelerates commissioning.
Key specs include a 235 A amperage rating, 600 V voltage rating, 50/60 Hz frequency, three-phase configuration, and a 30.71 in depth, 87.32 in height, and 60.12 in width footprint with a 1894 lb weight. Enclosure is NEMA 12, with floor mounting and top/bottom cable entry. The unit features integral disconnect and compliance with IEEE 519 and IEC 61000 standards.
Yes. The Eaton HCU2235D6N12 is designed to meet IEC 61000-3-2 and IEC 61000-3-4 requirements, and it complies with IEEE Std. 519. These standards address harmonic current limits and power quality performance, helping facilities avoid penalties and maintain reliable operation across industrial loads.
Industries with heavy nonlinear loads—such as steel, chemical processing, data centers, and large motor drives—benefit most. These units mitigate harmonics, reduce voltage distortion, and improve power factor. As a result, there are fewer nuisance trips, lower energy costs, and easier regulatory compliance in environments with stringent power quality requirements.
Warranty terms specify one year from installation or eighteen months from shipment, whichever occurs first. Eaton provides standard selling-policy support, and customers should expect access to documentation, spare parts, and technical assistance to support installation, commissioning, and ongoing operation for maintaining power quality over the unit’s life cycle.
