Eaton Z48G28T30SS Transformer - UL Listed Class 1 Div 2
Part Number: Z48G28T30SS
Quick Summary
The Eaton Z48G28T30SS transformer delivers reliable power conversion for hazardous locations in industrial facilities. Operators often face safety risks and costly downtime when equipment isn’t certified for Class 1 Division 2 environments. UL Listed protection, a NEMA 3R enclosure, and Grade 304 stainless steel construction support safer operation in hazardous locations. This transformer also aligns with 50/60 Hz industrial power systems and provides flexible outputs to simplify panel design and procurement. For engineers, the 30 kVA rating, 480 V primary, and 208Y/120 V secondary deliver predictable performance while enabling easier procurement and standardization across control panels. The encapsulated design minimizes enclosure footprint and reduces maintenance in space-constrained electrical rooms, delivering long-term reliability in demanding environments.
