FAQs
The N48M48T4516 supports floor or wall mounting and comes in a sturdy FR942 frame with a NEMA 2 enclosure. For installation, ensure adequate clearance for ventilation, align with floor or wall mounting provisions, and verify that the 611 lb weight is handled with appropriate equipment. This setup allows straightforward integration into existing electrical rooms or panel boards with minimal footprint.
This transformer is three-phase with a 480 V primary and a 480 Vac-208Y/120 Vac secondary, enabling flexible voltage routing to 480 V systems and 208Y/120 V auxiliary circuits. It operates at 60 Hz and provides 45 kVA of rating, making it suitable for medium-power distribution in automation and manufacturing environments.
Yes. The 480 V primary and 480 Vac secondary (with 208Y/120 V options) support common industrial distribution schemes. Its K-Factor nonlinear design and DOE 2016 efficiency further enhance performance under variable loads typical of machine cells and assembly lines.
The unit is UL Listed and aligned with DOE 2016 efficiency standards (10 CFR Part 431). These certifications facilitate regulatory compliance, energy-performance targets, and procurement approvals within regulated facilities.
The warranty follows Eaton's policy: one year from installation or eighteen months from shipment, whichever occurs first. DOE 2016 efficiency reduces energy consumption over the transformer’s life, lowering operating costs and improving return on investment in continuous-operation environments.
