AC-23 is the category for switching motor loads and other highly inductive circuits — the 32 A rating is the current the switch can make and break under those conditions, not just carry. Breaking capacity is 256 A at 400 V AC-23B; making capacity is 320 A at the same voltage. That means it can interrupt a fault current up to 256 A and close onto a fault up to 320 A, which covers most downstream short-circuit scenarios when the upstream fuse is sized correctly. Short-circuit withstand with BS-type fuses is 80 kA at 400 V — the switch body itself will hold under a fault up to that level as long as the associated fuse clears it. The making capacity under fault conditions is also rated 80 kA with BS fuses. ## Panel integration and mounting Mounts on a DIN rail or plate — the body dimensions are 96 mm wide (3.8 in) by 112 mm deep (4.4 in) by 98 mm high (3.9 in). That 96 mm width is standard for a 4-pole switch-disconnector in the TeSys GS family, so it fits existing panel cutouts and rail spacing without surprises. Power circuit terminals accept 6 to 25 mm² flexible copper, terminated with screw terminals torqued to 3.2 N·m. Control circuit terminals use the same torque. The IP20 rating with the terminal cover fitted means it's touch-safe for general industrial panel use but not for wet or dusty environments without an enclosure. ## Standards and compliance Designed to IEC 60947-3 (switch-disconnector standard), with fuse-links per IEC 60269-1 and IEC 60269-2. The body is rated for both AC and DC networks, with a rated insulation voltage (Ui) of 750 V AC and impulse withstand voltage (Uimp) of 8 kV. Fire resistance of the body material is 960 °C per IEC 60695-2-1 — a glow-wire test that confirms the housing won't propagate a flame under fault conditions. Protective treatment is TH (tropicalized), meaning it's treated against humidity and fungal growth for use in warm, damp environments. ## Durability and operating range Mechanical durability is 10,000 cycles; electrical durability is 1,500 cycles in AC-23A/B and 300 cycles in DC-23A/B. The DC rating is lower because DC arcs are harder to extinguish — if the application is DC, factor in the reduced cycle life. Ambient operating temperature range is -20 °C to +70 °C, which covers most indoor industrial panel conditions. The 32 A thermal current rating is at 40 °C ambient; derate above that per the standard IEC curve. ## Sourcing and lifecycle Sourced to order against the BOM quantity.","metaTitle":"GS1DBR4 TeSys GS fuse switch disconnector body, 32 A, 4P","metaDescription":"Schneider Electric TeSys GS GS1DBR4 fuse switch disconnector body, 32 A, 4 poles, BS type, 400 V AC.
