It carries a 63 A rated continuous current (Iu) across three poles, with a rated insulation voltage of 800 V and a max AC operational voltage of 690 V at 50/60 Hz. The front-terminal busbar connection suits it for panel-mounted isolation duty where you need a visible disconnect without overcurrent protection built in. ## What the undervoltage release means for your circuit That's standard for applications where you need the load to stay off after a brownout or power loss: conveyors, pumps, or any motor circuit where an automatic restart could be a safety or process risk. The UVR has no leading contact, so it doesn't provide early warning ahead of the dropout. The 3VA1163-1AA32-0DA0 shares the same 70 mm depth, 76.2 mm width, and 130 mm height as the rest of the 3VA1 160 A frame family. The front terminal accepts busbar connection for the main circuit — no lug terminals here, so plan for a busbar system rather than ring-tongue or fork crimps. An optional motor drive can be added externally if remote operation is needed. The lifecycle stage is listed as current, meaning Siemens still produces this order code as an active catalog item. No successor has been announced.","metaTitle":"Siemens 3VA1163-1AA32-0DA0 Switch Disconnector, 63 A, UVR","metaDescription":"Siemens SENTRON 3VA1 switch disconnector, 63 A rated continuous current, 3-pole, undervoltage release 208-230 V AC.

However, the 3VA1163 uses busbar connection on the front terminal, while the 3VA1112 uses lug terminals — you may need to adapt the busbar arrangement or add busbar adapters.
