Eaton Z48D47T75CUSS4X Hazardous Transformer - Class 1
Part Number: Z48D47T75CUSS4X
Quick Summary
Eaton Z48D47T75CUSS4X Hazardous Transformer is a rugged encapsulated unit designed for Class 1 Division 2 locations and critical power distribution in demanding environments. Operators often struggle with uptime when equipment sits in corrosive or crowded spaces, making maintenance risky and costly. This transformer combines copper windings, an EPTZ design, and a NEMA 4X enclosure to protect both personnel and assets while delivering reliable power. With a 75 kVA rating and three-phase operation, it supports scalable loads and simplifies integration with standard switchgear. The product aligns with hazardous-location safety practices and durable enclosure standards, enabling safer installations and long-term cost efficiency for industrial facilities and energy-intensive processes.

Feature → Business Impact → Application: Copper windings provide low impedance and efficient energy transfer, reducing copper losses and improving overall efficiency, which translates to lower operating costs in continuous-duty service. This supports reliable power for motors and controls in manufacturing lines and chemical processing plants. Feature → Encapsulated EPTZ design offers robust protection against moisture, dust, and chemical exposure, translating into longer service intervals and reduced field maintenance in harsh environments such as upstream oil & gas facilities. Application: hazardous locations with washdown or chemical handling where downtime is costly. Feature → 75 kVA three-phase rating matches moderate-to-heavy load profiles common in distribution panels and sub-systems; Business Impact → scalable capacity with minimal footprint, enabling phased upgrades without transformer swaps. Application: mid-size plants needing durable power conversion from 480 V to 480Y/277 V. Feature → Tap size 2 at +2.5% FCAN and 2 at -2.5% FCBN provides voltage regulation to handle site fluctuations; Business Impact → improved voltage stability and equipment protection; Application: sites with variable supply voltage or long cable runs. Feature → NEMA 4X enclosure with Weathershield Indoor-Outdoor support reduces ingress and corrosion risk; Business Impact → faster installation and lower maintenance costs in harsh environments; Application: outdoor substations, chemical plants, and marine/offshore facilities. Feature → Class 1 Division 2 hazardous-location rating and rugged construction enable compliant operation in hazardous zones; Business Impact → regulatory alignment and safer operation; Application: process industries and refineries where strict safety standards apply.

FAQs
For Class 1 Division 2 installations, ensure the transformer is installed within the NEMA 4X enclosure as specified, with proper clearance for cooling and access to the tap settings. Verify compatibility with existing switchgear and verify that all wiring and termination practices follow local codes and Eaton guidelines. Use appropriate grounding and ensure humid or chemical exposure is minimized by enclosure integrity.
The Z48D47T75CUSS4X provides two taps at +2.5% FCAN and two taps at -2.5% FCBN to compensate for voltage drop or rise along distribution feeders. This enables tighter voltage control at the secondary 480Y/277 V under varying load conditions, improving equipment performance and reducing nuisance tripping due to undervoltage or overvoltage conditions.
Yes. The unit is a three-phase transformer with a 480 V primary and a 480Y/277 V secondary, designed for hazardous locations (Class 1 Division 2) and encapsulated for protection. It is appropriate for powering lighting, controls, and small motors in hazardous environments, provided installation follows the specified enclosure and rating requirements.
Certifications are listed as manufacturer-specific in the data; Eaton notes the product is designed for hazardous locations with a Class 1 Division 2 rating and a NEMA 4X enclosure. For explicit certification marks (CE, SIL, IP, etc.), consult Eaton's documentation or contact the manufacturer to confirm current compliance for your region and application.
Encapsulation and a NEMA 4X enclosure protect windings from moisture, dust, and contaminants, reducing field maintenance and risk of insulation breakdown. This translates to longer mean time between failures (MTBF), lower repair costs, and improved uptime for critical processes in chemical plants, oil & gas facilities, and other harsh environments, delivering a favorable total cost of ownership.
