Eaton Z20N11E07CU Transformer - Class I Div 2, 7.5 kVA
Part Number: Z20N11E07CU
Quick Summary
Eaton hazardous location encapsulated transformer provides safe power conversion for rugged hazardous-area systems. Facilities struggle with enclosure integrity, regulatory compliance, and uptime in Class I Division 2 environments. UL Listed certification, Class I Division 2, Groups A–D, and a NEMA 3R enclosure protect against moisture, dust, and incidental weather exposure. Designed for indoor-outdoor use with a 50/60 Hz frequency and copper windings, it supports reliable control power while reducing downtime. The 7.5 kVA rating and compatibility with 120/240 V secondary circuits help streamline installation and inventory management for industrial automation projects.
