Breaking capacity is 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. The 121 kA at 240 V gives headroom for high-fault utility feeds; the 11.9 kA at 690 V is the limiting value for IEC installations. At 55 °C it derates to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. Maximum power loss is 17.3 W — negligible for panel heat budget but worth noting for sealed enclosures.","metaTitle":"Siemens 3VA1063-4ED42-0JA0 SENTRON MCCB, 63 A, 4-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1063-4ED42-0JA0 molded case circuit breaker, 63 A rated at 40 °C, 4-pole, 121 kA breaking capacity at 240 V.
