Marine Generator / Alternator · Power Generation
Leroy-Somer LSA 42.3 125kVA 400V 50Hz is a Marine Generator / Alternator within the Power Generation category. It is typically installed in the engine room or generator room, coupled to a prime mover and connected to the vessel’s main or emergency electrical distribution system. Its engineering role is to convert mechanical shaft power into electrical power for shipboard consumers. The complete model designation should be retained when matching drawings, certificates, service information and spare parts because neighboring variants may differ in configuration even when they share the same equipment family. The exact shipboard arrangement and interfaces remain installation-specific and should be checked against the vessel’s approved drawings and equipment documentation.
