Eaton LY48D28T06CUSS Marine Duty Transformer - UL Listed
Part Number: LY48D28T06CUSS
Quick Summary
The Eaton LY48D28T06CUSS marine duty encapsulated transformer delivers reliable power conversion for onboard systems. In harsh salt-air environments and constant vibration, ordinary transformers can corrode or drift voltage, causing unplanned downtime. UL Listed safety certification and a NEMA 3R Grade 304 stainless enclosure provide rugged protection for indoor-outdoor marine service. With copper windings and a 60 Hz three-phase design, it integrates into existing power-distribution schemes, reducing installation risk and lifecycle costs. Designed for 480 V input and 208Y/120 V output, it supports common marine equipment, control panels, and auxiliary systems. Warranty terms, service accessibility, and Eaton's documented catalog support help procurement teams mitigate risk during project kickoff.

FAQs
The LY48D28T06CUSS is a 6 kVA, three-phase transformer with a 480 V primary and 208Y/120 V secondary, designed for 60 Hz marine service. Its copper windings and encapsulated design support rugged onboard electrical systems, and it connects via the 72B06L wiring configuration. This enables reliable voltage regulation across critical loads in harsh environments.
Install this transformer per the Eaton datasheet and use the 72B06L wiring configuration for primary and secondary connections. Ensure correct load distribution and follow the recommended torque and shutdown procedures. Mount in the NEMA 3R Grade 304 stainless enclosure for indoor-outdoor service and provide adequate clearance for ventilation and heat dissipation.
Yes. The transformer is designed for marine duty with a rugged indoor-outdoor NEMA 3R enclosure and UL Listed safety, supporting reliable operation in offshore electrical rooms. Its 6 kVA rating and copper windings ensure consistent 480 V to 208Y/120 V conversion at 60 Hz, even under challenging platform conditions. That durability supports long service intervals and reduces maintenance crew calls.
UL Listed safety certification applies to this transformer, confirming compliance with electrical safety requirements. The unit's Grade 304 stainless steel enclosure and NEMA 3R rating provide corrosion resistance for indoor-outdoor marine environments. It also aligns with standard marine practice for copper-wound, encapsulated transformers. UL listing supports procurement validation and regulatory audits, while the copper windings and 60 Hz specification match common shipboard systems.
Encapsulated, copper-wound transformers like LY48D28T06CUSS require minimal maintenance due to sealed construction that resists moisture and dust ingress. The 6 kVA rating supports efficient load handling, helping avoid over-sizing and related capex. With UL safety and durable enclosure, you should experience higher uptime, lower unplanned downtime, and reduced service interventions on vessels.
