It is not a circuit breaker — there is no overload or short-circuit protection built in. The part is designed for isolation and switching duty only, carrying a maximum power loss of 38 W at full load. Rated operational voltage reaches 690 V AC (50/60 Hz) and 500 V DC, with a rated insulation voltage Ui of 800 V. ## Undervoltage release and switching duty No auxiliary contacts are fitted; the UVR is the only integrated trip device. The disconnector accepts a motor drive as an optional extension, so remote switching is possible without replacing the base unit. ## Panel fit and connections Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm high — a 3-pole MCCB footprint that fits standard Siemens 3VA panel cutouts and busbar systems. Main circuit connections are busbar-type on the front terminals, which simplifies busbar stacking in a distribution panel but means you need the matching busbar adapters rather than ring-tongue lugs. The 2 kA limited-time rating (1 s and 0.5 s) tells you the short-time withstand capability for coordination studies — this disconnector can pass fault current for up to 1 second at 2 kA without damage, which matters when sizing upstream protection.","metaTitle":"Siemens 3VA1112-1AA32-0DA0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA32-0DA0 switch disconnector, 3-pole, 125 A rated continuous current, no overload/short-circuit protection, with undervoltage release 208-230V AC.
