It carries a breaking capacity of 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that define its fault-interruption capability for line protection duty. The unit measures 130 mm high, 76.2 mm wide, and 70 mm deep, so it fits the standard SENTRON 3VA mounting footprint on a DIN rail or panel baseplate. Above that, the TM210 release begins to derate: 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. The storage range is wider because the breaker is not carrying current or switching during storage — that limit governs handling, not running. No official successor has been issued for this order code. The SENTRON 3VA series remains the active platform for Siemens molded case circuit breakers in this frame size.","metaTitle":"Siemens 3VA1063-4ED36-0BH0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1063-4ED36-0BH0 molded case circuit breaker, 63 A rated, 121 kA breaking at 240 V.
