For motor duty, the rated operational current is 1000 A at 400 V AC-23B, which covers switching of mixed resistive and inductive loads including motors up to 560 kW at 400 V. Breaking capacity is 10,000 A at 400 V AC-23B; making capacity is 8,000 A at the same voltage. These figures tell you the disconnector can safely close onto and interrupt fault currents up to those levels — essential for selectivity coordination downstream of a transformer or large motor branch. ## Standards and approvals — which IEC specs govern fit The body is designed to IEC 60947-3 (switch-disconnectors) and the associated fuse standards IEC 60269-1 and IEC 60269-2. The fuse accommodation is BS type, size D1 — this is the British Standard fuse-links family, not DIN or UL; confirm the fuse-links in your BOM match BS 88 or similar. Fire resistance is tested to IEC 60695-2-1: the body withstands 960 °C, the fuse cover 850 °C. This is a glow-wire test for flammability — relevant for panel builders certifying to IEC 61439 or similar. ## Lifecycle and sourcing — active production, quoted to order The body accepts power circuit bars up to 100 mm² (five bars) or screw terminals up to 185 mm² flexible. Tightening torque for the power circuit is 44 N·m. The IP20 protection rating applies with the terminal cover fitted — this is touch-safe but not washdown-rated.","metaTitle":"GS1VBR3 TeSys GS Fuse Switch Disconnector Body, 1250 A, 3P","metaDescription":"Active GS1VBR3 fuse switch disconnector body, 1250 A, 3-pole, BS fuse size D1.
