The 63 A rating holds steady from 40 °C up to 50 °C (still 63 A), then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C — so if your enclosure runs hot, you lose only about 8% at the top end. The 3-pole design and line-protection tuning (thermal-magnetic trip curve for cable and busbar protection) make this a straight fit for main or feeder duty in a distribution panel. Breaking capacity drops with voltage: 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. ## Built-in undervoltage release and auxiliary switch complement A trip indicator is present on the front face, so a walk-by inspection catches a tripped state without opening the panel door. The 3VA1163-4EF36-0CH0 measures 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in). ## Environmental and thermal limits","metaTitle":"Siemens 3VA1163-4EF36-0CH0 SENTRON MCCB, 63A, 121kA at 240V","metaDescription":"Siemens 3VA1163-4EF36-0CH0 SENTRON molded case circuit breaker, 63A rated, 121kA breaking at 240V. 3-pole, line protection, undervoltage release.

The 3VA1163 is a larger frame (160 A frame vs 100 A frame) — it is 76.2 mm wide, while the 3VA1110 is narrower. Busbar centers and mounting hole pattern differ. Also the 3VA1163 has a higher breaking capacity (121 kA vs lower on the 3VA1110), so the fault-current rating may be mismatched for the original panel design. Requires a panel layout review and possibly busbar rework."},{"question":"What compliance documentation does Siemens provide for 3VA1163-4EF36-0CH0?","answer":"As a SENTRON MCCB, it carries IEC/EN 60947-2 certification. Siemens provides a declaration of conformity for CE marking, and UL/CSA listings are available on the specific variant.
