Feature: Class 1 Division 2 encapsulated design with copper winding provides explosion-suppression and durable insulation. Business Impact: minimizes ignition risk and reduces maintenance costs in hazardous zones. Application: ideal for control panels and power distribution in chemical processing, refining, and offshore facilities. Feature: 45 kVA rating backed by copper windings supports critical loads with headroom for motor starters and instrumentation, enabling fewer transformers in a plant and reducing capital spend. Application: substations, MCCs, and equipment rooms that demand reliable service. Feature: Primary 480 V and secondary 208Y/120 V wiring offers immediate compatibility with existing plant distributions, minimizing rework and facilitating rapid deployment. Business Impact: faster commissioning and reduced wiring errors. Application: PLC panels, VFDs, and instrumentation cabinets. Feature: 60 Hz three-phase operation with an 80 °C rise rating enables robust performance in warm environments, supporting compact layouts and higher ambient temperatures. Business Impact: improved reliability in confined spaces and during peak loads. Application: process control rooms and machine centers. Feature: NEMA 3R enclosure with Grade 304 stainless steel provides weatherproof protection for indoor-outdoor service. Business Impact: enables outdoor installations, reduces corrosion risk, and lowers long-term maintenance. Application: outdoor substations, pump stations, and hazardous-area rollouts. Feature: Tap size 2 at -5% FCBN delivers voltage regulation to downstream equipment, reducing voltage fluctuations and extending equipment life. Business Impact: steadier processes and fewer sensor faults. Application: motor starters, relays, and automation controllers. Warranty and service considerations: Eaton’s standard warranty policy offers protection against manufacturing defects for up to one year from installation or eighteen months from shipment, whichever occurs first, ensuring long-term support for critical infrastructure.

FAQs
For Class 1 Division 2 installations, mount the Z48G28B45CUSS in a protected space with adequate ventilation and access for routine maintenance. Ensure wiring follows local codes for hazardous locations, use copper conductors, and respect the 15.68 in depth and 46.23 in width footprint. Verify input and output connections (480 V to 208Y/120 V) match your distribution scheme.
Key specs include a 45 kVA volt-ampere rating, 480 V primary, 208Y/120 V secondary, three-phase configuration, and a 60 Hz frequency. The transformer uses copper windings and supports a 80 °C rise, with a two-tap -5% FCBN option to help regulate downstream voltages for sensitive equipment.
Yes. The Z48G28B45CUSS employs a Grade 304 stainless steel enclosure and a NEMA 3R rating, making it suitable for indoor-outdoor service. Its weatherproof construction and encapsulated design reduce moisture ingress and corrosion risks, allowing reliable operation in exposed outdoor substations and protected indoor areas alike.
This transformer is UL Listed, reflecting compliance with recognized safety standards. It features a Grade 304 stainless steel enclosure and NEMA 3R rating, supporting safe outdoor operation. The product is designed for Class 1 Division 2 hazardous locations (Groups C and D) and uses copper windings suitable for demanding industrial use.
Total cost of ownership includes initial capital, installation, and ongoing maintenance.
