It handles 690 V AC (50/60 Hz) or 600 V DC, making it a straight fit for 400 V three-phase distribution and DC bus isolation in the same enclosure. That simplifies BOM sizing for a warm cabinet or a line-side disconnect near a motor drive. The front terminals accept busbar connection, which means it drops into a panel busbar system without extra adapters. IP40 on the front keeps finger probes out; the rest of the enclosure is the panel's own IP rating. ## Undervoltage release and lifecycle The optional motor drive allows remote operation if the panel is hard to reach. The width matches standard 4-pole MCCB footprints, so it should fit existing panel cutouts or DIN-rail layouts without re-drilling.","metaTitle":"Siemens 3VA1163-1AA42-0CC0 SENTRON 4-Pole Switch Disconnecto","metaDescription":"Siemens 3VA1163-1AA42-0CC0 SENTRON 4-pole switch disconnector, 63 A rated continuous current, 690 V AC / 600 V DC, IP40 front, undervoltage release included.
