GF and GAF contactors

A compact and efficient way to switch DC loads

Optimal for central inverters
ABB offers the widest range of compact contactors for DC load switching in low

voltage power distribution. Thanks to their breaking performance of DC circuits,
GF contactors will switch DC-PV3 inverter loads up to 1325 A 1500 V DC and
GAF contactors will switch DC loads up to 2050 A 1000 V DC-1.
