That Ith figure is the continuous current the bare body can carry in open air; once you add fuses and enclose it in a panel, you'll derate per the enclosure's thermal rise. The body accepts T4 DIN fuses and is rated for both AC and DC networks. Rated operational current (Ie) hits 1000 A at 400 V in AC-23A and AC-23B duty — that's the heavy motor and mixed-load category per IEC 60947-3, so this disconnect handles inrush from motors, transformers, and resistive-inductive combinations without derating. At 690 V AC-23A/B it drops to 630 A; at 500 V it's 800 A. For DC applications with two poles in series per phase, it carries 1000 A at 440 V in DC-23A and DC-23B. The GS1V3 is rated for 10000 A making and breaking capacity at 400 V AC-23B. That's the maximum prospective fault current it can safely close into and interrupt under those conditions. The short-circuit making capacity (Icm) is 100 kA at 400 V when protected by gG (gI) fuses rated up to 1000 A — meaning the fuse does the heavy fault clearing, and the switch body must survive the let-through. Rated impulse withstand voltage (Uimp) is 12 kV, and rated insulation voltage (Ui) is 1000 V AC 50/60 Hz, so it's built for 690 V systems with margin. ## Mechanical and electrical endurance — what to expect in cycle life Mechanical durability is 5000 cycles — that's the number of no-load open-close operations before wear affects the mechanism. Electrical durability varies by duty: 500 cycles in AC-23A and AC-23B, 100 cycles in DC-23A and DC-23B. For a disconnect that's operated infrequently (isolation, not switching), that's adequate. If you're cycling it daily under load, track the count. The body has a direct frontal operating handle. Power circuit connections accept bars or screw terminals up to 185 mm² flexible cable; tightening torque is 44 N·m for both. IP20 with terminal cover fitted — finger-safe but not washdown, so keep it inside the enclosure. Protective treatment is TH (tropicalized humidity resistance). Fire resistance: fuse cover passes 850 °C glow-wire test, body passes 960 °C per IEC 60695-2-1.","metaTitle":"GS1V3 TeSys GS fuse switch disconnector, 1250 A, 3P","metaDescription":"GS1V3 TeSys GS fuse switch disconnector body, 3 poles, DIN mount, 1250 A thermal current, 100 kA making capacity.
