It carries a continuous current rating of 63 A that holds flat across the entire operating temperature range from 40 °C to 70 °C — no derating curve to manage, which simplifies panel thermal budgeting for a 63 A load-break position. Rated operating voltage is 690 V AC and 500 V DC, with an insulation voltage of 800 V. The front-terminal connection accepts lug or clamp terminations for the main circuit, and the unit mounts on a DIN rail in a standard 70 mm depth × 76.2 mm width envelope — a direct fit into existing SENTRON 3VA panel layouts. ## Undervoltage Release — UVR 120–127 V AC This variant ships with an integrated undervoltage release (UVR) rated for 120–127 V AC, 50/60 Hz. No auxiliary contacts are fitted on this order code; the UVR is the only auxiliary release. The UVR does not include a leading contact, so the release operates directly on the undervoltage condition without a time-delay or make-before-break auxiliary. For applications needing a motor-drive option, the product extension for an optional motor drive is available, though it is not included at this order-code level.","metaTitle":"Siemens 3VA1163-1AA36-0CA0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA36-0CA0 SENTRON switch disconnector, 63 A rated current flat to 70 °C, 3-pole, 690 V AC / 500 V DC, undervoltage release 120-127 V AC.

They share the same 70 mm × 76.2 mm × 130 mm footprint and front-terminal connection, so a panel cutout designed for the MCCB variant will accept the switch disconnector without rewiring, provided the protection scheme is handled upstream."},{"question":"How do I get current pricing and availability for 3VA1163-1AA36-0CA0?","answer":"Submit an RFQ through this listing.
