No stock-holding claim is made; each quote reflects real-time supply. ## 800 A Fuse Switch Disconnector for Motor & Power Circuits This is a TeSys GT fuse switch disconnector body (GS1T), 3 poles plus neutral, accepting BS-type fuse links. The rated operational current reaches 800 A at 400 V in AC-23B duty, which covers switching of motor loads and other high-inductive circuits where the making and breaking current exceeds the thermal rating. Making capacity is 8000 A at 400 V AC-23B; breaking capacity is 6400 A at the same duty. These figures define the fault-closure and interruption capability — the disconnector can close onto a fault up to 8 kA and safely break up to 6.4 kA, which is sufficient for most industrial panel fault levels when backed by upstream protection. Rated insulation voltage (Ui) is 1000 V AC, and impulse withstand (Uimp) is 12 kV, confirming suitability for 690 V line-to-line systems with adequate clearance for surge events. ## Mechanical & Environmental Fit for Panel Integration Dimensions are 19.7 in (501.5 mm) wide by 10.2 in (260 mm) deep by 10.6 in (268 mm) high. Mounting is via rail plate — plan the enclosure backplate layout accordingly; the width is the critical dimension for multi-unit row spacing. Power circuit terminals accept bars up to 2 × 0.09 in² (60 mm²) or 5 × 0.10 in² (63 mm²). Tightening torque for the power circuit is 389.4 lbf·in (44 N·m) — a torque wrench is required; under-torquing risks thermal rise at 800 A. Operating temperature range is -4 to 158 °F (-20 to 70 °C) with storage from -40 to 176 °F (-40 to 80 °C). The IP20 degree of protection with the terminal cover fitted means the body is touch-safe but not sealed against moisture — install inside a suitable enclosure in wet or dusty environments. ## Durability & Standards Compliance Mechanical durability is rated at 6000 cycles; electrical durability varies by duty — 500 cycles in AC-23A/B and 100 cycles in DC-23A/B. For a motor-switching application at 800 A, budget the electrical life at the AC-23B figure of 500 operations before contact inspection is due. Complies with IEC 60269-2 (fuse coordination), IEC 60947-3 (switch-disconnector), and IEC 60269-1 (general fuse requirements). Fire resistance is 1760 °F (960 °C) for the body and 1562 °F (850 °C) for the fuse cover per IEC 60695-2-1 — relevant for panel fire-risk assessments. Protective treatment is TH, indicating tropicalized humidity protection — suitable for non-condensing high-humidity environments without additional conformal coating.","metaTitle":"Schneider Electric GS1TBR4 TeSys GT Fuse Switch Disconnector","metaDescription":"Active GS1TBR4 TeSys GT fuse switch disconnector body, 3P+N, BS fuse type, rated 800 A at 400 V AC-23B.
