The IP40 front protection keeps dust and tools out of the enclosure cutout, but the back and sides rely on the panel's own IP rating. ## Shunt trip and auxiliary contact complement The front-terminal busbar connection keeps wiring clean on a DIN-rail or mounting-plate layout; the 101.6 mm width and 70 mm depth fit standard 160 A frame cutouts. Rated insulation voltage Ui is 800 V, and maximum operational voltage is 690 V AC (50/60 Hz) or 600 V DC — so it's suitable for 400/480 VAC industrial panels and 600 VDC battery or solar circuits. The rated short-time withstand (2 kA for 1 s or 0.5 s) covers the conditional short-circuit rating when backed by an upstream protective device.","metaTitle":"Siemens 3VA1163-1AA42-0KH0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0KH0 switch disconnector, 63 A rated continuous current, 4-pole, IP40 front, shunt trip 220-250 V DC / 208-277 V AC.
