The 4-pole design (3 poles + switched neutral) makes it suitable for three-phase systems where the neutral needs isolation. Front terminals accept busbar connection for the main circuit, which keeps wiring tidy in a distribution panel. Mounts in a standard MCCB cutout — 70 mm depth, 101.6 mm width, 130 mm height. The front terminals and busbar connection mean the busbars run across the front, not the rear, so plan the busbar routing accordingly. The two auxiliary switches (HP) are pre-installed and wired; they provide status feedback without needing a separate auxiliary contact block. Optional motor drive available for remote operation.","metaTitle":"Siemens 3VA1163-1AA42-0AB0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0AB0 switch disconnector, 63 A rated current flat to 70 °C, 4-pole, IP40 front, 70 mm depth.
