Feature: Marine duty encapsulated design with copper windings. Business Impact: Enhanced durability in harsh marine conditions reduces corrosion and maintenance intervals, improving uptime for critical loads. Application: Ideal for offshore platforms and vessel electrical rooms where exposure to salt spray and humidity is common. Feature: Copper windings and low-loss construction. Business Impact: Higher efficiency and lower thermal rise translate to cooler operation and reduced energy waste, cutting operating costs over the life of the asset. Application: Suitable for continuous service in 60 Hz, three-phase distribution networks across 480 V to 208Y/120 V schemes. Feature: Tap changer capability (2 at +2.5% FCAN, 2 at -2.5% FCBN). Business Impact: Tight voltage regulation to compensate for line drop and load changes, preserving equipment performance and protecting sensitive electronics. Application: Critical in installations with long feeders or marginal supply networks. Feature: NEMA 3R enclosure with indoor-outdoor weatherability. Business Impact: Enables outdoor placement without additional enclosures, accelerating installation timelines and reducing equipment footprint. Application: Suitable for outdoor equipment rooms, decks, and exposed switchgear areas on ships and offshore rigs. Feature: 60 Hz, three-phase, 480 V primary to 208Y/120 V secondary, 15 kVA rating. Business Impact: Aligns with common industrial and marine power standards, enabling seamless integration and scalable power distribution. Application: Supports mid-range load centers and critical auxiliary systems demanding reliable, regulated power. Feature: UL Listed certification and robust enclosure design. Business Impact: Simplifies procurement and compliance processes while delivering documented safety assurance. Application: Meets regulatory expectations for electrical equipment in marine and industrial environments. Feature: Compact footprint with defined dimensions (20 in W × 17.38 in H × 10.52 in D) and 296 lb weight. Business Impact: Easier onboarding into space-constrained electrical rooms and enables predictable installation planning. Application: Suitable for retrofit or new builds where space is at a premium.
