FAQs
This transformer uses a three-phase 60 Hz supply with a 480 Delta primary and 208Y/120 V secondary. Plan for adequate clearance around the ventilated enclosure, ensure proper fan availability if external cooling is used, and verify mounting on a CASE B frame suitable base. The compact 17 in x 26.5 in footprint simplifies panel integration.
The unit features a K-Factor nonlinear design, which enhances thermal performance under nonlinear loading. With a 15 kVA rating at 60 Hz and aluminum windings, it maintains voltage stability and reduces overheating risk. For installations containing drives or high harmonic content, ensure proper ventilation and consider the UL Listed safety features.
Yes. The N48M28T15SRTRS64X-US comes with a NEMA 4X enclosure design and a CASE B frame, enabling robust outdoor and indoor installations. It is UL Listed and tested for sound per NEMA ST-20, which supports operation in challenging environments while maintaining safety and reliability.
Confirm the primary voltage is 480 Delta and the secondary voltage is 208Y/120 V to match the service needs. Also verify 60 Hz compatibility, 15 kVA rating, and three-phase connection. The tap settings (2 at +2.5% and 4 at -2.5%) help regulate voltage under varying loads, aiding seamless replacement without major panel rework.
The ventilated, aluminum-wound design reduces heat buildup, improving efficiency under nonlinear loads and lowering cooling costs. UL Listing and NEMA ST-20 compliance support regulatory alignment, while the rugged CASE B enclosure reduces field service calls. Over time, this can translate to lower maintenance spend and a faster return on investment for mission-critical applications.
