Breaking capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V; at 690 V it still manages 17 kA. That kind of headroom matters when you're coordinating downstream protection in a high-fault industrial distribution board — the breaker stays intact and clears the fault before the upstream transformer trips. The built-in undervoltage release (UVR) means this breaker drops out when supply voltage falls below a set threshold — useful on motor feeders where you want to prevent automatic restart after a sag. Ambient operating range runs from -25 °C to 70 °C, with full 63 A rating holding up to 50 °C; above that it derates stepwise to 56.7 A at 70 °C. Storage range is wider: -40 °C to 80 °C, which covers most job-site conditions before the panel is energized. Depth is 70 mm, width 76.2 mm, height 130 mm, so it fits standard SENTRON 3VA1 panel cutouts and busbar arrangements without rework. This 3-pole MCCB snaps onto a standard DIN rail or mounts via the rear panel cutout — the 70 mm depth and 76.2 mm width match the SENTRON 3VA1 family footprint. No auxiliary contacts are fitted from the factory (auxiliary contact version: without), so if you need status feedback to a PLC, plan to add the external auxiliary trip block (order code 3VA9608-0BB11). The undervoltage release is internal, wired separately to a control voltage. If your design calls for Modbus or ground-fault monitoring, step up to a 3VA1 with the electronic release option.","metaTitle":"Siemens 3VA1163-6EF36-0BA0 SENTRON MCCB, 63 A, 220 kA at 240","metaDescription":"Siemens 3VA1163-6EF36-0BA0 SENTRON molded case circuit breaker, 3-pole, 63 A rated, 220 kA breaking at 240 V, TM240 release, undervoltage release.
