Eaton Z25M48T75 Transformer - Class 1 Div 2 UL Listed
Part Number: Z25M48T75
Quick Summary
Eaton hazardous location encapsulated transformer delivers reliable power isolation for hazardous industrial environments like chemical plants, refineries, and mining sites. Engineers often face compatibility, safety, and regulatory challenges when installing equipment in Class 1 Division 2 locations. UL Listed, NEMA 3R enclosure, and Class 1 Division 2 Groups C and D certification provide critical safety and regulatory confidence. Designed for indoor-outdoor service, 50/60 Hz operation, and a 75 kVA rating, it enables scalable, reliable power delivery with fewer field adjustments. For procurement teams, that translates to faster approvals, lower risk of compliance audits, and predictable downtime.
