Eaton Specification Sheet - 315C364G03
Compatibility with AQB-A101/A103 and NQB-A101/A103 breakers provides plug-and-play integration, reducing field rewiring and enabling quick upgrades in existing panels. For procurement teams, this translates to shorter lead times and lower project risk. Engineers benefit from consistent mounting alignment across multiple vessels, aiding standardization and streamlining maintenance cycles. The 500 VAC and 250 VDC ratings cover diverse shipboard loads, while three-pole protection ensures reliable fault isolation in demanding environments. Front connection and a single-pole imperial mounting base simplify wiring routes, enable straightforward retrofits, and reduce enclosure modification needs. Naval class design combines rugged materials and corrosion resistance with a compact footprint, supporting reliable operation in harsh maritime conditions. UL Listed certification further ensures safety compliance, minimizing regulatory hurdles during audits and inspections. With a footprint of 8.2 in L Ă— 4.4 in W Ă— 3.2 in H and a weight of 2.5 lb, the unit fits tight switchgear spaces without compromising performance. Catalog notes NSN 5925-00-832-6143 aid global sourcing, while compatibility with AQB/NQB breakers reduces spare-part inventories and stockouts. This mounting solution is ideal for naval switchgear upgrades, shipboard power system modernization, and marine panelboard installations requiring proven reliability and straightforward installation.
