Eaton Z48G11S25CU Hazardous Transformer - UL Listed
Part Number: Z48G11S25CU
Quick Summary
Z48G11S25CU hazardous location transformer delivers safe isolation for industrial control panels in Class I Division 2 sites. Too many standard transformers pose ignition risks or require complex retrofits when deployed in hazardous zones. UL Listed construction with a NEMA 3R enclosure and Class I Division 2 rating provides compliant, durable performance. Copper windings and a 25 kVA rating support scalable power distribution from 480 V to 120/240 V in rugged environments. This combination reduces downtime, simplifies installation, and helps meet safety and electrical codes across oil, gas, and chemical facilities.

Encapsulated in a robust housing, the Z48G11S25CU is specifically designed for hazardous locations, reducing ignition risk and enabling safe operation in Class I Division 2 environments. The design integrates compact geometry with EPZ (Explosion Protected Zone) features, delivering reliable protection where flammable atmospheres are present. With 25 kVA power rating and copper windings, the transformer delivers stable voltage from a 480 V primary to 120/240 V secondary at 50/60 Hz. The -5% FCBN tap setting supports precise voltage regulation to match load variations in sensitive control panels, improving uptime and reducing equipment stress. UL Listed and sealed in a NEMA 3R enclosure, the unit is qualified for indoor-outdoor service while resisting moisture, dust, and weathering. Its frame 182H and 2D wiring connections simplify integration with existing electrical distribution and control systems. Installation is streamlined by the device’s standardized footprint and rugged construction, minimizing field modifications and commissioning time. The 115°C temperature rise specification provides a clear thermal margin for continuous operation under peak loading in harsh environments. This combination provides long-term value with certified safety, reliable performance, and predictable maintenance costs for oil, gas, chemical, and other hazardous-site applications.
