The 800 V rated insulation voltage (Ui) gives headroom for 690 VAC systems, and the interrupting ratings climb to 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at 690 VAC — so it handles high-fault-current points of common coupling without cascading upstream. ## Thermal derating and auxiliary contacts Above that it derates: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. ## Panel fit and mechanical endurance The 4-pole MCCB measures 101.6 mm wide, 130 mm tall, and 70 mm deep — a standard SENTRON 3VA footprint that drops into existing panel layouts without re-drilling. Front-face protection is IP40.","metaTitle":"Siemens 3VA1063-4ED42-0BH0 SENTRON MCCB, 63A, 4P, 121kA at 2","metaDescription":"Siemens 3VA1063-4ED42-0BH0 SENTRON molded case circuit breaker, 63A rated, 4-pole, TM210 release, 121kA at 240V.
