Eaton Z48G28T75SS Hazardous location transformer - UL Listed
Part Number: Z48G28T75SS
Quick Summary
The Eaton hazardous location transformer provides reliable 480 V to 208Y/120 V power in Class 1 Division 2 zones. In hazardous environments, equipment downtime and maintenance costs spike when transformers aren’t designed for strict safety and rugged conditions. UL Listed with a Grade 304 stainless steel enclosure, this unit also features a 115°C rise and aluminum windings for durability. For project teams, the combination of Class 1 Division 2 capability, indoor-outdoor ratings, and 75 kVA capacity translates to reduced wiring complexity and faster installation. Designed for three-phase 480 V input with secondary 208Y/120 V, it supports 50/60 Hz operation and a -5% FCBN tap setting for voltage tuning. This combination helps facilities meet evolving safety codes while maximizing uptime and reducing total cost of ownership.
