FAQs
The N48M28F3021CULS40 is designed for 480-208Y/120 three-phase power distribution and comes UL Listed, simplifying safety approvals. With dimensions of 21.13 in L, 24.88 in W, and 36.88 in H and a weight of roughly 398 lb, it fits common electrical rooms and retrofit projects while maintaining accessible service clearances.
K13 K-Factor indicates the transformer's ability to tolerate non-linear loads without excessive overheating or distortion. It improves voltage regulation under high crest-factor conditions and reduces winding stress, enabling more stable operation in environments with variable-speed drives and harmonics common in modern manufacturing and data-center equipment.
Yes. The 30 kVA, three-phase N48M28F3021CULS40 is well-suited for data centers and manufacturing environments due to its vented design for heat management, K-Factor protection for nonlinear loads, and UL Listed safety certification. Its 480-208Y/120 primary/secondary configuration supports typical facility power architectures and helps maintain uptime.
This unit is UL Listed, confirming safety compliance for industrial installations. UL certification simplifies procurement and reduces risk during inspection, enabling faster commissioning in regulated facilities. While UL is the primary certification listed, the transformer’s K-Factor (K13) also informs performance expectations with nonlinear loads.
Expected ROI comes from improved power quality, reduced downtime, and longer transformer life due to better heat management and robust K-Factor performance. Maintenance is straightforward: monitor vented cooling, verify connections, and inspect for any signs of thermal stress. The UL Listed build supports consistent reliability in demanding industrial environments.
