Eaton S48N11S25X General-Purpose Transformer - UL Listed
Part Number: S48N11S25X
Quick Summary
Engineered as an Eaton S48N11S25X general-purpose encapsulated transformer, it reliably steps 480 V to 120/240 V for control panels. Facilities often contend with bulky transformers and heat buildup that increase downtime and complicate service. UL Listed certification and a NEMA 3R enclosure support safe indoor-outdoor operation, while 50/60 Hz compatibility keeps equipment in spec. This transformer delivers a robust 25 kVA rating and compatible 480 V primary to 120/240 V secondary for diverse industrial loads. In short, it balances reliability, safety, and ease of installation to drive efficiency and uptime in manufacturing environments. Its aluminum coil and encapsulated design also reduce weight and improve heat dissipation in compact footprints.
