That 63 A holds flat through 50 °C; at 55 °C it derates to 60.48 A, then 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C — so if your panel ambient runs hot, the continuous rating drops, and you size the load accordingly. Interrupting capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That 121 kA at 240 V covers high-fault utility feeds; the 75.6 kA at 415 V handles most industrial distribution. ## Footprint and auxiliaries — what fits in the DIN space Width 76.2 mm, depth 70 mm, height 130 mm. That 76.2 mm width is a standard 3-pole MCCB footprint — three 25.4 mm modules — so it drops into the same DIN-rail slot as other SENTRON 3VA frames.","metaTitle":"Siemens 3VA1163-4EF32-0HH0 SENTRON MCCB, 63 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1163-4EF32-0HH0 SENTRON molded case circuit breaker, 63 A rated, 3-pole, 121 kA at 240 V interrupting capacity.
