FAQs
LY48G24T03CU provides a 480 V primary and 240 V secondary in a three-phase, 60 Hz configuration. It is rated at 3 kVA, making it suitable for mid-size motor loads and control circuits aboard vessels or in harsh industrial environments. The copper windings improve efficiency and thermal performance, while the tap setting of 2 at -5% FCBN assists voltage regulation under load changes.
Yes. The transformer is designed as a marine duty encapsulated unit with a NEMA 3R enclosure and indoor-outdoor weathershield, providing robust protection against moisture, dust, and salt exposure. It is UL Listed, offering a recognized safety standard for on-board power distribution and shore-side installations in demanding marine settings.
Plan for a three-phase, 60 Hz supply at 480 V with a 240 V secondary, and ensure space for a 124 lb unit with dimensions around 8.26 in by 13.4 in by 15.93 in. The wiring connection uses 74A03L, and there is a 2 tap at -5% FCBN, supporting voltage regulation during load changes. Also verify UL-listed mounting and outdoor installation suitability.
