Eaton Z48D28B45CU Hazardous Location Transformer - UL Listed
Part Number: Z48D28B45CU
Quick Summary
Eaton Hazardous location encapsulated transformer delivers safe, reliable power isolation for equipment in hazardous environments such as chemical plants and oil refineries. The primary challenge in these settings is maintaining uptime while meeting stringent safety standards and regulatory requirements. This transformer carries UL Listed certification, a Class 1 Division 2 rating for Groups C and D, and a rugged NEMA 3R enclosure, which together support compliant installation in harsh, dusty, or damp environments. It also aligns with copper-windings performance and a 50/60 Hz duty cycle, ensuring stable voltage transfer from 480 V to 208Y/120 V without excessive losses. In practice, this means reduced maintenance overhead, predictable operation, and a lower total cost of ownership for critical loads.

FAQs
The Z48D28B45CU is designed for Class 1 Division 2 locations with a rugged NEMA 3R enclosure and UL Listed certification. Plan for civil work that supports a heavy 1651 lb transformer, ensure proper seismic and mechanical mounting, provide adequate ventilation and clearance for heat dissipation, and use appropriate cabling rated for 480 V primary and 208Y/120 V secondary. Crane access or hoist points are advised for installation due to its weight, and follow Eaton’s installation guidelines for tap settings and wiring connections (65F).
This transformer delivers 45 kVA with a 480 V primary and 208Y/120 V secondary, configured as a three-phase unit operating at 50/60 Hz. It uses copper windings and includes taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN for voltage regulation. The device has an 80 °C rise rating and a NEMA 3R enclosure, suitable for indoor-outdoor environments.
Yes. It is specifically rated as Class 1 Division 2, Groups C and D, encapsulated for added safety, with a NEMA 3R enclosure for protective outdoor exposure. UL Listed certification confirms compliance with applicable electrical codes, supporting safe operation in potentially explosive atmospheres while maintaining reliable power transfer for critical loads.
Key certifications include UL Listed for electrical safety and a Class 1 Division 2 rating for hazardous locations, complemented by a durable NEMA 3R enclosure. These certifications matter because they streamline regulatory approvals, reduce installation risk, and enable confidence when wiring to sensitive loads in chemical plants, refineries, and similar facilities where ignition sources must be controlled.
The unit carries a one-year warranty from installation or eighteen months from shipment, whichever comes first. Maintenance considerations include normal transformer upkeep, inspection of cooling pathways, and routine checks of tap settings and connections. Its copper windings and robust enclosure support long service life, translating to lower maintenance costs and fewer unscheduled outages.
