It is built to the IEC frame 160 footprint — 70 mm deep, 76.2 mm wide, 130 mm tall — and connects via front busbar terminals. Unlike a molded case circuit breaker, this unit provides no overload or short-circuit protection; it is a straight disconnect switch for isolating a load circuit under load or no-load conditions. Rated for AC operation up to 690 V (50/60 Hz) and DC up to 500 V, it handles the voltage levels common in industrial distribution panels, motor control centers, and switchgear assemblies. ## Auxiliary contacts and switching duty The auxiliary contacts allow remote monitoring of the disconnect position — useful for a line-down diagnostic or for interlocking with a downstream starter. Maximum power loss is 38 W at rated current — a figure to consider for thermal management inside a sealed panel, especially if multiple disconnectors are ganged. The part accepts an optional motor drive for remote operation, but no undervoltage release or communication module is fitted from the factory. The 70 mm depth and 76.2 mm width match the IEC frame 160 cutout common across the 3VA1 series. Front busbar connection simplifies bus-stack assembly in a distribution panel. The nut keeper kit (included per the description) aids torque retention on the busbar bolts — a detail that matters when the panel sees vibration from adjacent contactors or drives.","metaTitle":"Siemens 3VA1163-1AA32-0AH0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA32-0AH0 SENTRON switch disconnector, 63 A rated continuous current, 3-pole, IEC frame 160, IP40 front.
