Its rated operational current (Ie) hits 1000 A at 400 V in both AC-23A (occasional switching of motor loads) and AC-23B (infrequent switching) duty classes. For DC applications, two poles in series per phase carry 1000 A at 440 V under DC-23A/B. The making capacity (Icm) is 100 kA at 400 V when protected by gG (gI) fuses rated 1250 A — that's the short-circuit making rating, not the breaking rating, and it depends on the upstream fuse coordination. ## Standards, Mounting, and Integration Built to IEC 60947-3 (switch-disconnector standard), IEC 60269-1, and IEC 60269-2 (fuse standards). The body accepts DIN-type fuses size T4. Rated insulation voltage (Ui) is 1000 V AC, impulse withstand (Uimp) 12 kV — typical for a heavy-duty industrial disconnector in a main panel or machine supply. The operating handle is on the right side. Power circuit connections accept bars or screw terminals up to 185 mm² flexible cable, torqued to 44 N·m. Fire resistance tested: fuse cover withstands 1562 °F (850 °C) per IEC 60695-2-1, body 1760 °F (960 °C). Protective treatment is TH (tropicalized — resistant to heat and humidity).","metaTitle":"TeSys GS1VD4 Fuse Switch Disconnector Body, 1250 A, 4P","metaDescription":"GS1VD4 is an active TeSys GS fuse switch disconnector body, 4 poles, DIN mount, rated 1250 A thermal current, 1000 A at 400 V AC-23A/B, breaking 10 kA at 400 V.
