The 125 A rated continuous current (Iu) sets the maximum load it can carry continuously without exceeding temperature limits. The 800 V rated insulation voltage (Ui) and 690 V AC / 500 V DC maximum operational voltages define the system voltage it can safely interrupt — common for 400 V three-phase distribution or 480 V industrial feeds. The short-time withstand ratings of 2 kA at both 0.5 s and 1 s tell you it can hold off fault current for that duration while an upstream breaker clears, but this is not a breaker itself; coordination relies on the upstream protective device. ## Integration notes The 70 mm depth, 76.2 mm width, and 130 mm height match the standard 3VA1 frame footprint, so it occupies the same DIN-rail or mounting-plate space as a 3-pole MCCB in the same series. The busbar connection on the front terminal means it accepts plug-in busbar links rather than lugged cable — verify your panel's busbar system compatibility before specifying.","metaTitle":"Siemens 3VA1112-1AA32-0KA0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA32-0KA0 switch disconnector, 125 A rated current, 3-pole, shunt trip release 220-250 V DC / 208-277 V AC.
