Eaton Z48N11S01A Hazardous Location Encapsulated Transformer - UL Listed
Part Number: Z48N11S01A
Quick Summary
Eaton Hazardous location encapsulated transformer provides safe, compact power conversion for hazardous industrial facilities. In harsh environments where ignition risks and downtime threaten production, a rugged, compliant transformer is essential. This model features UL Listed safety certification, a NEMA 3R enclosure, and EPZ design suitable for Class I Division 2 locations, supporting indoor-outdoor installations. The device converts 480 V primary power to 120/240 V secondary for control circuits and small loads, with a 1 kVA rating. By combining robust enclosure, sealed winding, and certified construction, it minimizes maintenance and enhances system reliability while aligning with 50/60 Hz operation. This makes it ideal for automation panels, motor controls, and hazardous-area distributions in manufacturing and processing facilities.
