Same 630 A rating holds at 690 V AC-23A/B, and the conventional free-air thermal current (Ith) is also 630 A at 40 °C — so the derating from enclosure mounting or elevated ambient is the only factor that reduces usable current below that figure. Breaking capacity at 400 V AC-23B is 5040 A, making capacity 6300 A — the switch can clear faults up to that level without external fuse assist, though the short-circuit making capacity with BS fuses reaches 630 kA at 400 V for installations on high-fault-current networks. ## Panel fit — 550 mm wide, 348 mm high, 260 mm deep At 550 mm wide and 348 mm high, this is a large disconnector requiring a substantial enclosure cutout — verify the back panel layout against the 260 mm depth plus cable bending radius for the screw terminals accepting up to 300 mm² flexible conductors. Mounting support is plate or rail, and the IP20 rating with terminal cover means it is suitable for enclosed panel installation where the enclosure door provides the environmental seal — not for standalone outdoor use. Tightening torque for the power circuit is 44 N·m — a torque wrench is required for the M12-class terminals; the 0.5 in² (300 mm²) flexible cable capacity suits large feeder conductors typical of 630 A distribution. ## Active production — no lifecycle risk for BOM planning This is a current-production part in the TeSys GS range, so it can be specified into new panel designs and ordered against BOM quantities without end-of-life contingency. Standards compliance covers IEC 60269-1 (fuse), IEC 60947-3 (switch-disconnector), and IEC 60269-2 (fuse for industrial applications) — the fire resistance of the body is 960 °C per IEC 60695-2-1, and the fuse cover is rated 850 °C. Electrical durability is 1000 cycles in AC-23A/B and 200 cycles in DC-23A/B; mechanical durability is 6000 cycles — these set the maintenance interval for applications with frequent switching, such as motor start/stop cycles or load-bank switching.","metaTitle":"Schneider GS1SBR4 TeSys GS Fuse Switch Disconnector, 630 A","metaDescription":"Schneider GS1SBR4 TeSys GS fuse switch disconnector body, 4 poles, BS fuses, rated 630 A at 400 V AC-23A.
