It is a pure disconnect: no overload release, no short-circuit protection, no undervoltage release. That makes it a load-break switch for isolation and maintenance lockout, not a protective device. The front terminal busbar connection keeps wiring clean in a panel, and the IP40 front face suits enclosed switchgear where splash protection isn't required. Insulation voltage is rated 800 V, operating voltage 690 V AC or 500 V DC, so it handles 480 V and 600 V class systems with margin. Mechanical life is 15,000 operating cycles typical, which is adequate for a disconnect that sees daily but not continuous switching. This disconnect mounts in the same 76.2 mm wide, 130 mm tall, 70 mm deep envelope as the 3VA1 MCCB family — it drops into the same DIN-rail or screw-mount footprint. The front terminal busbar connection means you run the buswork straight in from the front, not the rear, which simplifies panel layout and busbar routing. The optional motor drive (listed as optional) allows remote switching if needed. At 38 W max power loss, it won't cook adjacent components, but leave a little breathing space in a dense row.","metaTitle":"Siemens 3VA1112-1AA32-0AF0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA32-0AF0 switch disconnector, 125 A continuous at 40-70 °C, 3-pole, IP40 front.
