The Schneider Electric A9GSB292 is an Acti9 SBI fuse-disconnector, a 2-pole switch rated for 690 V AC that accepts 22 x 58 mm fuses up to 125 A. It's built to IEC EN 60947-3, which covers the making, carrying, and breaking of currents under normal and specified overload conditions — the standard that governs disconnect switches in industrial panels. The AM GG fuse curve means it's intended for motor-circuit protection, where the fuse needs to handle inrush without nuisance blowing while still clearing a fault.
The 70 mm width (8 x 9 mm pitches) takes up two module spaces. Terminals accept 1.5 to 50 mm² rigid or 2.5 to 35 mm² flexible cable, with a 12 mm strip length and 4 N·m tightening torque. That's a solid grip for the 125 A rating; make sure the ferrule is seated fully before torquing.
Environmental and installation notes
The switch is not padlockable, so if lockout/tagout is required at the disconnect point, you'll need a separate provision.
