The 63 A rating holds flat from 40 °C to 50 °C, then derates to 58 A at 70 °C — so in a warm panel you still get full current up to 50 °C. The 121 kA interrupting rating at 240 V is the headline number, but at 415 V it's still 75.6 kA, and at 690 V it drops to 11.9 kA. That matters if you're coordinating with downstream breakers in a 480 V system: the SCCR at 415 V is well above typical utility fault levels. The TM210 release is a standard thermal-magnetic curve — no electronic adjustment, no communication, no voltage trip. It's a workhorse for fixed-load feeder protection. The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall — that's a 3-inch wide footprint, so it fits standard Siemens SENTRON mounting bases. Three poles, no auxiliary switch or undervoltage release fitted as standard (the base switch carries provision for up to 3 auxiliary switches HQ).","metaTitle":"Siemens SENTRON 3VA1063-4ED32-0AD0 MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1063-4ED32-0AD0 molded case circuit breaker, 3-pole, 63 A rated at 40°C, 121 kA breaking at 240 V.
