It is NOT a circuit breaker; there is no overload or short-circuit release inside. This is a manual disconnect with an undervoltage release (UVR) that drops the load when control voltage falls below the dropout threshold. Rated continuous current Iu of 63 A means the switch can carry this current continuously without exceeding temperature limits — sized for a 63 A feeder or motor branch circuit where isolation is needed, not protection. The 3-pole design handles three-phase circuits up to 690 V AC 50/60 Hz or 500 V DC. The undervoltage release (UVR) is factory-set for 120-127 V AC control power; if that supply dips, the switch opens automatically — useful for undervoltage protection or emergency-off circuits where a loss of control voltage should disconnect the load. That gives you status feedback for both the switch position and a trip event from the UVR, all in one package without needing a separate auxiliary block. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — the standard 3VA1 frame 160 footprint. Front terminals accept busbar connection for the main circuit; the auxiliary contacts and UVR terminals are on the front face. The nut keeper kit (included per the description) helps hold busbar connections during installation. Maximum power loss is 38 W — negligible for most panel thermal budgets, but worth checking if you're packing several in a small enclosure. ## What it swaps with — and what it doesn't Physically, the 3VA1163-1AA32-0CH0 shares the same 70 x 76.2 x 130 mm footprint as the 3VA1110-5EE32-0DC0 (a 100 A line-protection MCCB). Both use front terminals and fit the same panel cutout. But functionally they are different animals: the 3VA1110 is a full molded-case circuit breaker with a TM220 thermal-magnetic release; this switch disconnector has no overcurrent protection. If the BOM calls for a disconnect-only device, the 3VA1163 fits. If the panel was designed around the 3VA1110's breaker function, you'd need to add separate fuses or a motor-protective breaker upstream.","metaTitle":"Siemens 3VA1163-1AA32-0CH0 Switch Disconnector, 63 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1163-1AA32-0CH0 switch disconnector, 63 A rated continuous current, 3-pole, with undervoltage release 120-127V AC.
