Eaton T48M11E05NV Transformer - Dry Type DS-3
Part Number: T48M11E05NV
Quick Summary
The Eaton Transformer T48M11E05NV provides reliable dry-type distribution for 5 kVA single‑phase applications. Engineers often wrestle with heat buildup, space constraints, and enclosure protection in compact control panels. Certification details vary by market; common references include CE and UL and IP-based protections—verify with Eaton for your region. Built around a DS-3 design with aluminum windings and electrostatic shielding, this transformer supports efficient operation in demanding environments. With a primary of 480 V and secondary 120/240 V, it easily integrates into standard industrial panel boards and machine controls. Field taps at +2.5% FCAN and -2.5% FCBN enable voltage fine-tuning to minimize nuisance trips. Warranty coverage follows Eaton policy, providing post-install support for peace of mind.
