The Siemens 3VA1116-1AA32-0AE0 is a SENTRON 3VA1 switch disconnector in an MCCB-style molded case, rated for 160 A continuous current (Iu) across 3 poles. It provides no overload or short-circuit protection — this is a pure disconnect and isolation device, not a circuit breaker. The front busbar connection and 4 HQ auxiliary switches (4 CO contacts) suit it for applications where you need a visible-break isolation point with status feedback, such as in motor feeder disconnects or main incomer switches in distribution panels.
Rated continuous current Iu of 160 A means this switch disconnector can carry 160 A continuously without exceeding its thermal limits — sized for a 160 A feeder or motor circuit. Rated insulation voltage Ui of 800 V and max operational voltage of 690 V AC (50/60 Hz) or 500 V DC cover standard low-voltage distribution up to 690 V line-to-line. The 3-pole design with front busbar connection integrates into a standard 76.2 mm wide (3-inch) DIN-rail or panel-mount footprint, matching the 3VA1 frame size common across the SENTRON family.
Mounts on a DIN rail or panel with the same 70 mm depth, 76.2 mm width, and 130 mm height as other 3VA1 frame devices. The front terminal arrangement for the main circuit and the nut keeper kit (included per the description) simplify busbar or cable connection from the front.
