It is designed for isolating and protecting motor circuits and other inductive loads, providing visible isolation and fuse protection in a single package. The making capacity is 500 A at the same voltage, so it can close onto a fault without welding contacts. Rated operational power reaches 25 kW at 400 V, 33 kW at 500 V, and 45 kW at 690 V, giving a clear selection curve for three-phase motor applications across common European voltage levels. The AC-23B rating is the key selection parameter: it covers occasional switching of motor loads, including inching and plugging. The 50 A rated operational current at 400 V AC-23B means this unit is sized for motor circuits drawing up to that full-load current, not just resistive heater loads. Short-circuit withstand is 10.6 kA, backed by a making capacity of 100 kA at 400 V when protected by gG fuses. This tells the panel builder that the switch can handle high prospective fault currents upstream, provided the fuse coordination is correct. The IP20 protection (with terminal cover) means it is suitable for installation inside an enclosure where tools are required to access live parts — standard for panel-mount switchgear. This is a switch-disconnector, not a contactor for frequent switching; it is meant for isolation and occasional load-break, not continuous duty cycling. The GS2FG3 is designed and tested to IEC 60947-3, the standard for switch-disconnectors and fuse-combination units. This covers isolation performance, making and breaking capacities, and temperature rise limits. Fire resistance is verified: the fuse cover withstands 850 °C and the body 960 °C per IEC 60695-2-1, which is relevant for compliance with enclosure flammability requirements.","metaTitle":"Schneider Electric GS2FG3 TeSys GS Switch-Disconnector-Fuse,","metaDescription":"Obsolete TeSys GS switch-disconnector-fuse, 3P, 50 A (AC-23B), 400 V breaking capacity 400 A.
