It accepts DIN-style fuses in size 00, making it a straightforward fit for fuse blocks already on the plate. Rated operational current hits 160 A at 400 V AC-23A and AC-23B, and 125 A at 690 V under the same duty classes. Breaking capacity is 1280 A at 400 V AC-23B; making capacity reaches 1600 A at the same voltage. Short-circuit withstand is 22.7 kA — the fuse does the interrupting, but the switch body must hold together through the fault. That number tells you the mechanical bracing is there. The AC-23A and AC-23B duty ratings cover switching of motor loads and other highly inductive circuits. AC-23A is the standard motor-switching category per IEC 60947-3; AC-23B allows occasional switching of motors at higher currents. Both are rated here at the same 160 A at 400 V, which simplifies selection — no need to pick a derated variant for motor duty. Three protected poles (3t) means all three phases have fuse monitoring — if a fuse blows, the switch can signal or lock out. Rated insulation voltage is 750 V AC, impulse withstand 8 kV — adequate for 400 V and 690 V systems with typical overvoltage category III. The IP20 finger-safe terminal cover meets IEC 60529, so it's suitable for enclosed panels where operators might reach in. Mounts on a plate (not DIN rail) — expect to drill and tap or use a backplate. The external left-side operating handle means the switch mechanism extends out the side, so plan clearance for handle swing and door interlock if used as a main disconnect. Power circuit terminals accept bars up to 20 mm² or ring-tongue lugs from 50 to 95 mm². Tightening torque is 12 N·m — a standard torque wrench setting for M8-class power terminations. Wire bending space per IEC 60947-1 applies; don't crowd the lugs against the enclosure wall. Dimensions: 190 mm wide, 162 mm tall, 136.5 mm deep. The depth includes the fuse carrier and handle mechanism — verify clearance behind the panel door, especially if a deep enclosure is not available. No cross-reference to a different part number is needed — this is the active, un-replaced variant. Fire resistance: the fuse cover withstands 850 °C (IEC 60695-2-1), the body 960 °C. Electrical durability is 1000 cycles for AC-23A and AC-23B, 200 cycles for DC-23A and DC-23B. Mechanical durability is 10,000 cycles — the switch mechanism outlasts the electrical contacts under heavy switching.","metaTitle":"TeSys GS GS2LLG3 Switch-Disconnector-Fuse, 160 A, 3P, DIN","metaDescription":"Schneider Electric TeSys GS GS2LLG3 switch-disconnector-fuse, 160 A rated operational current, 3 poles, DIN fuse size 00.
