It is a pure disconnect device: no overload or short-circuit protection (no trip unit, no undervoltage release), so it serves as a manually operated load-break switch for isolation and maintenance locking. Rated insulation voltage is 800 V, with operating voltages of 690 V AC and 600 V DC — suitable for 400/480 V three-phase panels and 600 V DC bus applications. The 3VA1112-1AA46-0AA0 mounts into a panel cutout for MCCB-style devices. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth — standard for the 3VA1 IEC frame 160 family. The front terminal layout matches the same footprint as other 3VA1 4-pole disconnectors, so a panel wired for a 3VA1112-5EE32-0AA0 will accept this unit without rewiring, provided the auxiliary contact and release options match (this variant carries none). Mechanical service life is 15,000 operating cycles typical — adequate for daily isolation in a production line over many years.","metaTitle":"Siemens 3VA1112-1AA46-0AA0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA46-0AA0 switch disconnector in MCCB design. 125 A continuous, 690 V AC / 600 V DC, 4-pole, front terminal.
