The 2 kA short-time withstand (1 s and 0.5 s) means it can pass fault current up to that level while the upstream breaker clears, so it coordinates with a 2 kA SCCR panel. The IP40 front protection keeps tools and fingers out but is not sealed against washdown — indoor panel use only. ## Deployment context Mounts via busbar connection with front terminals — designed for panel mounting on a busbar system, not DIN rail. The 76.2 mm width (3-pole) and 130 mm height fit standard MCCB panel cutouts. The undervoltage release (UVR) at 24 V DC allows integration into safety circuits: if the UVR coil loses power, the disconnector opens, providing a controlled isolation on control-voltage loss — typical for emergency-stop chains or undervoltage protection schemes.","metaTitle":"Siemens 3VA1163-1AA32-0BC0 Switch Disconnector, 63 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1163-1AA32-0BC0 switch disconnector, 63 A rated continuous current, 3-pole, 690 V AC / 500 V DC, with undervoltage release 24 V DC, 2 auxiliary switches.
