It provides manual load isolation and safe disconnection under load, but carries no overload or short-circuit protection elements internally; it is a disconnect-only device, not a circuit breaker. The built-in undervoltage release (UVR) rated 208-230 V AC 50/60 Hz will trip the switch if control voltage drops, adding a layer of remote or protective shutdown for furnace or motor feeder circuits. ## Flat Thermal Curve — No Derating Between 40 °C and 70 °C That means a panel designer can size the busbar and connections for a constant 63 A without calculating temperature correction factors for the disconnector itself. The maximum power loss is 38 W at rated current, so the heat dissipated into the enclosure is predictable and moderate for a 63 A device. Mechanical service life is 15,000 operating cycles typical — adequate for infrequent manual switching or maintenance isolation, not for daily cycling under load. ## Panel Integration — Busbar Connection, Front Terminals The main current circuit connects via busbar connection at front terminals — no screw-clamp lugs for cable tails, so plan for busbar taps or adapter kits. The 76.2 mm width (3-inch footprint) and 70 mm depth fit standard MCCB panel cutouts and DIN-rail adapters. The undervoltage release coil is wired separately; verify control voltage matches the 208-230 V AC 50/60 Hz rating before energizing. The auxiliary switch block provides 3 CO contacts total (2 aux + 1 trip alarm), enough to report position and fault status to a control system.","metaTitle":"Siemens 3VA1163-1AA32-0DH0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA32-0DH0 switch disconnector, 63 A continuous at 70 °C, 3-pole, undervoltage release 208-230 V AC, IP40 front.

The 3VA1110-5EF32-0AM0 is a full molded case circuit breaker with TM240 thermal-magnetic overcurrent release (LI protection) and a 20,000-cycle mechanical life. The 3VA1163 is physically identical in the same 3VA frame (same 76.2 mm width, 70 mm depth, 130 mm height) so it can drop into the same panel cutout and busbar system, but the wiring for the UVR coil must be added.
