It is the disconnect body only; the fuse links and operating handle are ordered separately. The 160 A rating holds across AC-23A and AC-23B duty at 400 V and 500 V, which covers motor starting and mixed resistive-inductive loads. At 690 V with the terminal cover fitted, the operational current derates to 125 A. Breaking capacity is 1280 A at 400 V AC-23B; making capacity is 1600 A at the same duty. For high-fault installations, the rated short-circuit making capacity jumps to 100 kA at 400 V when backed by gG (gI) fuses rated up to 160 kA — meaning the disconnector coordinates with upstream fuses rather than relying on its own arc extinction for full fault interruption. The external left-side operating handle is ordered separately — the body ships without one. Power circuit connections accept bars or screw terminals, with a tightening torque of 12 N.m. Cable range for flexible conductors is 50 to 95 mm². The IP20 finger-safe terminal cover is required for the 690 V rating and for compliance with IEC 60529. Fuse size is T00, DIN type. The body is 3-pole and rated for both AC and DC networks. On DC circuits with two poles in series per phase, the operational current is 125 A at 440 V for DC-23A and DC-23B duty — a significant derate from the AC figure, so factor that into any DC bus disconnect application. ## Durability and environmental ratings Mechanical endurance is 10,000 cycles; electrical endurance is 1,000 cycles under AC-23A or AC-23B, dropping to 200 cycles under DC-23A or DC-23B. The fuse cover withstands 850 °C glow-wire (IEC 60695-2-1), and the body withstands 960 °C — relevant for panel builders needing fire-resistance documentation. Protective treatment is TH (tropicalized) for humid environments. Rated insulation voltage is 750 V AC; impulse withstand voltage is 8 kV. Standards compliance covers IEC 60269-1, IEC 60269-2, and IEC 60947-3 — the latter being the switch-disconnector standard that defines the making/breaking and isolation performance. Network frequency is 50/60 Hz.","metaTitle":"GS1LLG3 TeSys GS fuse switch disconnector, 3P, 160 A, DIN","metaDescription":"GS1LLG3 TeSys GS fuse switch disconnector body, 3 poles, 160 A rated at 400 V AC-23B, DIN mount, active production.
