Low voltage generators for marine applications

ABB supplies an extensive range of electrical products for demanding marine applications. Proven and reliable product solutions combined with true global support ensure world-class service for ship owners, operators, shipyards, OEMs, panel builders and integrators.

Standard series:

ABB low voltage (LV) standard marine generators are specifically designed for marine diesel gen-sets in main, auxiliary or emergency power generation. ABB standard 4-pole generators have proven themselves in demanding marine applications. They enable short delivery times and high reliability.


  • Short delivery times

  • Robust design for harsh marine environment

  • Compatible to all marine classifications
