It carries a rated operational power of 450 kW at 400 V and 400 kW at 690 V, with a breaking capacity of 6400 A at 400 V under AC-23B duty — meaning it can safely interrupt fault currents up to that level on motor circuits. The unit accepts BS-type fuses in size C3 and provides IP20 finger protection with the terminal cover fitted, so it belongs inside a locked enclosure or panel, not in a washdown area. This part is officially obsolete per the manufacturer's lifecycle record. No direct successor order code is listed. Mechanical durability is 8000 cycles, electrical durability is 1000 cycles at AC-23A and AC-23B — so this is a switch for infrequent operation, not a daily contactor replacement. The 12 kV rated impulse withstand voltage (Uimp) confirms it handles typical distribution transients. Mounting is plate-mount only, not DIN rail, and the power circuit terminals accept bars up to 63 mm² or ring lugs for 2 cables of 300 mm² or 185 mm². Tightening torque for the power circuit is 44 N·m — a substantial connection that needs the right tool.","metaTitle":"Schneider Electric GS2TB4 TeSys GS Switch-Disconnector-Fuse,","metaDescription":"Obsolete Schneider Electric GS2TB4 TeSys GS switch-disconnector-fuse, 4 poles, 800 A rated current, BS fuse size C3.
