Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — the 101.6 mm width (4-inch) is a standard 4-pole frame footprint for the 3VA1 series, so it fits existing cutouts and busbar spacing in SENTRON distribution boards. ## Key Ratings and Their Meaning Rated insulation voltage Ui is 800 V, and maximum operational voltage is 690 V AC 50/60 Hz or 600 V DC — so it is rated for 690 V three-phase systems (common in industrial distribution) and for DC circuits up to 600 V. The short-time withstand rating is 2 kA for 0.5 s and 1 s — this is the fault current the disconnector can carry momentarily without damage while upstream protection clears. It is not a breaking capacity rating; the disconnector is not designed to interrupt fault currents.","metaTitle":"Siemens 3VA1163-1AA42-0BH0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0BH0 switch disconnector, 63 A rated continuous current, 4-pole, with undervoltage release 24 V DC and 3 auxiliary contacts.
