It is designed to accept T4 DIN fuses and provides a visible break for safe isolation in DC and AC circuits up to 1000 V insulation voltage. The headline rating: 1000 A at 400 V AC-23A (motor switching duty) and 630 A at 690 V AC-23A. That AC-23A rating means it handles the high inrush of motor loads — not just resistive heating — so it is sized for real motor branch circuits, not just general disconnects. Breaking and making capacity are both 10000 A at 400 V AC-23B, and with upstream gG fuses the short-circuit making capacity (Icm) reaches 100 kA at 400 V. That SCCR headroom lets you coordinate downstream faults without cascading upstream. The body accepts power circuit bars or screw terminals up to 185 mm² flexible cable. Tightening torque for the power connections is 44 N.m. The direct frontal operating handle gives a clear visual indication of contact position. Mechanical durability is 5000 cycles; electrical durability varies by duty — 500 cycles for AC-23A/B, 100 cycles for DC-23A/B. That is typical for a high-current switch-disconnector; plan maintenance intervals accordingly. Designed to IEC 60269-1, IEC 60269-2, and IEC 60947-3 — the core standards for low-voltage fuses and switch-disconnectors. The fuse cover withstands 850 °C glow-wire test; the body withstands 960 °C per IEC 60695-2-1. Protective treatment is TH (tropicalized) for humidity resistance. Rated impulse withstand voltage (Uimp) is 12 kV, which covers overvoltage category III/IV in typical industrial distribution.","metaTitle":"TeSys GS1V4 Fuse Switch Disconnector Body, 1250 A, 4P, DIN","metaDescription":"GS1V4 TeSys GS fuse switch disconnector body, 4 poles, DIN rail, rated 1250 A at 400 V AC-23A.
