FAQs
Plan for sturdy mounting on a rigid base due to a 430 lb weight. The unit dimensions are 24.88 in wide, 21.13 in deep, and 36.88 in high, so allocate sufficient front, rear, and side clearance for ventilation and service access per Eaton installation guidelines. Allow extra space above for venting and routine maintenance.
K13 indicates a high level of non-linear harmonic support. The transformer is designed to limit overheating and reduce harmonic-related losses when fed by non-linear loads, improving reliability and life expectancy in systems with power electronics or fast-switching equipment.
Yes. With a 30 kVA three-phase rating and a primary/secondary of 480-208Y/120, it supports critical loads common in data centers and manufacturing lines. UL Listed and vented for better cooling, it helps maintain uptime and supports compliant, stable power distribution in demanding environments.
Based on the provided data, UL Listed is the stated certification. For projects with additional standards requirements, verify with Eaton or consult the latest specification sheet, which also lists the catalog number N48M28T3021CU and related performance details.
