It is designed for isolation and switching of circuits where overload or short-circuit protection is handled upstream or by a separate device — the listing explicitly notes it ships without overload protection and without short-circuit protection. Rated insulation voltage (Ui) is 800 V, with a maximum operational voltage of 690 V AC 50/60 Hz and 600 V DC. The 63 A rated continuous current (Iu) sets the maximum load this disconnector can carry continuously without exceeding its thermal limits. For a 4-pole device on a 160 A frame, this means the internal current path and busbar connections are physically sized for higher current, but the part is factory-limited to 63 A — it is not field-upgradable to a higher rating. The undervoltage release (UVR) is factory-fitted and designed for 24 V DC. The UVR does not include a leading contact; verify coil polarity and suppression for the DC circuit. This is the expected life under no-load or low-load switching; frequent loaded switching will reduce service life. ## Panel integration and connection The main current circuit uses busbar connection with front terminal arrangement. This means the disconnector is designed to plug onto a busbar system (typically Siemens 3VA busbar adapters) rather than accepting lug or cable terminations directly. The 101.6 mm width (4-inch form factor) and 70 mm depth fit the standard 3VA1 panel footprint; mounting holes and busbar slots align with the SENTRON 3VA family. An optional motor drive can be added via the product extension slot. No auxiliary contacts are included (0 CO contacts, auxiliary contact version 'Without'). If status feedback is needed, a separate auxiliary switch module must be ordered and fitted. The trip indicator is also absent — visual confirmation of the open/closed state comes from the handle position only.","metaTitle":"Siemens 3VA1163-1AA42-0BA0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA42-0BA0 SENTRON switch disconnector, 63 A rated continuous current, 4-pole, IEC frame 160.

The 3VA1112-5EF32-0CA0 is a full molded case circuit breaker (MCCB) with a TM240 thermal-magnetic trip unit rated at 125 A, offering LI protection. The disconnector is 4-pole and 101.6 mm wide; the MCCB is 3-pole and 76.2 mm wide, so they do not share the same panel cutout or busbar footprint. The disconnector cannot be substituted for an MCCB where overcurrent protection is required."},{"question":"Where can I buy the 3VA1163-1AA42-0BA0?","answer":"This part is sourced and quoted to order against an RFQ through independent industrial automation distribution.

The SENTRON 3VA series carries CE marking and is designed to meet IEC 60947-3 for switch-disconnectors. RoHS and REACH compliance declarations are available from Siemens support.
