Four poles handle three-phase plus neutral isolation, with a maximum AC operational voltage of 690 V and a DC rating of 600 V. With a maximum power loss of 38 W at rated current, the heat dissipated inside the enclosure is modest; still, cluster several of these in a sealed box and the cumulative heat needs ventilation planning. Physical dimensions — 70 mm depth, 101.6 mm width, 130 mm height — match the standard 3VA1 MCCB footprint, so it drops into existing panel cutouts and busbar layouts for that series without rewiring.","metaTitle":"Siemens 3VA1163-1AA42-0AF0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA42-0AF0 SENTRON MCCB-style switch disconnector.
