Eaton LY48M28B30CU Marine Duty Transformer - NEMA 3R

Marine duty encapsulated design with copper windings and a NEMA 3R enclosure delivers exceptional durability in harsh environments. The rugged construction reduces corrosion-induced outages and lowers long-term maintenance expenses, making it ideal for offshore platforms, ships, and coastal substations where reliable power distribution is essential. Copper windings minimize resistance losses and heat, improving efficiency under heavy loads. The 80 °C rise rating guides enclosure and cooling design, while the NEMA 3R enclosure provides splash and wind-driven ingress protection for marine installations. 30 kVA three-phase power conversion provides scalable load handling with a compact footprint. The 480 V primary and 208Y/120 V secondary configuration supports critical equipment with consistent voltage profiles, reducing the need for multiple transformers on site. The three-phase design also supports paralleling with shared or separate feeders, enabling straightforward upgrades as demand grows. Voltage regulation is enabled by taps at +2.5% FCAN and -2.5% FCBN, allowing on-site fine-tuning to maintain stable secondary voltages under load variations. This reduces equipment stress and protects sensitive electronics, supporting tighter uptime targets for critical loads. The taps enable quick voltage compensation to match generator or grid variations without replacing equipment. Indoor-outdoor rating and Weathershield design provide flexible placement and consistent performance across weather conditions, reducing the need for enclosure swaps when environments change at dockyards or offshore sites. This resilience supports installations near hot boilers, salt spray, or dusty environments while meeting regulatory and reliability requirements. Dimensions of 14.66 in depth, 26.58 in width, and 28.15 in height with a 799 lb weight inform installation planning, hoisting, and ventilation requirements, helping teams minimize field surprises and ensure compliant mounting in restricted spaces. For integration with Eaton or third-party switchgear, this unit uses standard wiring connections and mounting footprints to simplify field retrofits. UL Listed certification and Eaton warranty support reliability and compliance; coupled with copper windings and solid core design, this transformer delivers predictable performance, simplified maintenance planning, and long service life under demanding duty cycles. The warranty terms provide protection against field failures during the first eighteen months after shipment or one year after installation, whichever comes first.
