The 63 A rating holds steady through 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C — useful to know when the breaker sits in a warm enclosure near other heat sources. Breaking capacity is specified across multiple voltages: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — a 3-inch wide body that fits standard MCCB panel mounting patterns. IP40 on the front face, so it's fine for indoor distribution boards where incidental contact with tools or fingers is the concern; no washdown rating. Max power dissipation is 17.3 W, which factors into enclosure thermal calculations when grouping several breakers.","metaTitle":"Siemens 3VA1163-4EF32-0AA0 SENTRON MCCB, 63 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1163-4EF32-0AA0 SENTRON molded case circuit breaker, 63 A rated at 40 °C, 3-pole, TM240 release, 121 kA breaking capacity at 240 V.
