Selling Policy 25-000 - Distribution and Control Products and Services
Power rating and electrical specs are designed to deliver predictable performance: a 15 kVA rating with 480 V primary and 120 V secondary supports essential onboard systems while keeping footprint practical for marine panels. The business impact is steadier loads and fewer voltage-related faults, enabling safer equipment operation in constrained spaces. This transformer is ideal for shipboard distribution where space is at a premium and reliability is non-negotiable. Tap changes at +2.5% and -2.5% provide fine voltage regulation, reducing equipment wear and protecting sensitive devices; the application is continuous duty in variable power environments, such as propulsion or ballast systems. Copper windings offer high efficiency and thermal stability, lowering energy losses and maintenance costs over the service life. In critical installations, these design choices translate to lower operating expenses and longer intervals between servicing. The NEMA 2 enclosure supports indoor marine environments, while the WS11 Weathershield option can extend service life in exposed bays; this reduces corrosion risk and downtime during offshore missions. Frame 816 and 18.39 in length enable straightforward mounting in standard panels, with DS-3 single-phase topology simplifying wiring schemes for retrofit projects. Certifications and standards like UL Listed and ABS Certified ensure procurement alignment with stringent regulatory requirements, while a one-year warranty from Eaton provides risk mitigation for capital investments. The result is a compact, robust solution that aligns with industrial power distribution best practices and simplifies spec-to-installation workflows.
