It is designed for isolation and switching of circuits where overload or short-circuit protection is handled upstream or by a separate device — note the product version is explicitly 'in MCCB design' but configured as a switch disconnector without integral overcurrent releases. Rated for AC operation up to 690 V and DC operation up to 500 V. Front terminal busbar connection is typical for panel-mounting on a busbar system. ## Integration and Mounting Notes IP40 front protection is suitable for indoor panel environments. Mechanical endurance is rated at 15 000 latching cycles — this is a switch disconnector, not a daily-duty contactor; expect it in isolation applications where it sees a few operations per shift or less. Maximum power loss is 38 W — factor this into panel thermal calculations if multiple units are ganged in a sealed enclosure.","metaTitle":"Siemens 3VA1163-1AA32-0BA0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA32-0BA0 SENTRON switch disconnector, 63 A rated continuous current, 3-pole, undervoltage release 24V DC.

It will not drop into a panel designed for the switch disconnector without rewiring because the connection type differs — the 3VA1163-1AA32-0BA0 uses busbar connection, while the 3VA1112-5EF32-0CA0 uses lug terminals.
