          GAF contactors

          The compact efficient way to switch DC loads




          Optimised for central inverters                                                                             03

          ABB offers the widest range of compact contactors for DC load switching in low
          voltage power distribution applications. Due to their breaking performance for
          DC circuits, GAF contactors can switch DC loads of up to 2050 A 1000 V DC-1.
