The 125 A continuous rating sets the maximum uninterrupted current the switch can carry without exceeding its thermal limits. The 690 V AC rated operational voltage covers standard 400 V three-phase systems with headroom for 480 V or 600 V industrial supplies. The 500 V DC rating makes it usable in DC bus or battery bank isolation applications within that voltage ceiling. The front terminal connection with clamp-type terminals accepts standard lug or cable terminations for the main circuit. The 3VA1 frame measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact footprint that fits standard MCCB mounting positions in a distribution board or control panel. The front terminal arrangement keeps wiring accessible from the front, and the optional motor drive (listed as a product extension) allows remote switching if needed later.","metaTitle":"Siemens 3VA1112-1AA36-0AD0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA36-0AD0 switch disconnector, 125 A rated continuous current, 3-pole, 690 V AC / 500 V DC, IP40 front, current lifecycle stage.
