Rated operational current hits 160 A at 400 V under AC-23B duty, which covers motor switching with occasional overloads — the tough stuff, not just resistive heaters. The 4-pole body takes up standard panel space for a T00 fuse base. Terminals accept power circuit bars or screw terminals for 50 to 95 mm² flexible copper, with a tightening torque of 12 N.m. The operating handle mounts on the external left side, so plan that into your panel layout — it's not a center-mount or through-door rotary. ## Durability and Environment Mechanical durability is 10,000 cycles — that's the handle-and-mechanism life before wear shows. Electrical durability is 1,000 cycles under AC-23A or AC-23B, and 200 cycles under DC-23A or DC-23B. Fire resistance is 850 °C on the fuse cover and 960 °C on the body per IEC 60695-2-1, which is the glow-wire test for flammability in a fault scenario.","metaTitle":"GS1LLG4 TeSys GS Fuse Switch Disconnector Body, 160 A, 4P","metaDescription":"Schneider Electric GS1LLG4 TeSys GS fuse switch disconnector body. 4 poles, DIN mount, 160 A rated.
