It carries a conventional free air thermal current of 400 A at 40 °C, and its rated operational current reaches 400 A at 400 V under AC-23B duty — the category for switching motor loads and other highly inductive circuits. The AC-23B rating at 400 V governs motor switching: 400 A operational current and 132 kW rated power. At 690 V AC-23B, the current derates to 315 A but power climbs to 295 kW — the voltage step compensates. For DC circuits, the part is rated 315 A at 440 V with poles not juxtaposed (DC-23B), so it handles battery banks or DC bus isolation in the same enclosure. The short-circuit withstand of 80 kA and making capacity of 4000 A at 400 V AC-23B confirm it can close onto a fault without welding contacts — critical for safety isolation points. Mounts on a plate or rail. The body measures 271 mm wide, 205 mm high, 149 mm deep — fits a standard 300 mm deep enclosure with clearance for cable bends. Power connections accept bars or screw terminals for 185–240 mm² flexible cable; control circuit and power circuit both torque to 25 N·m. IP20 with terminal cover installed, so it's suited for enclosed panel use, not washdown zones.","metaTitle":"Schneider TeSys GS1QQB3 Fuse Switch Disconnector Body, 400 A","metaDescription":"Schneider Electric TeSys GS1QQB3 fuse switch disconnector body, 3 poles, BS type, rated 400 A at 400 V AC-23B.
