Three poles, 800 V rated insulation voltage, and a breaking capacity that scales from 75.6 kA at 240 V down to 7.5 kA at 690 V. The interrupting rating tells you where this breaker can be placed in the fault-current hierarchy. At 240 V it clears 75.6 kA — that is a high-capacity main or feeder position. At 415 V it still handles 52.5 kA, enough for most industrial secondary distribution. At 500 V and 690 V it drops to 7.5 kA, which is typical for a downstream branch breaker in a 690 V motor control center. At 19.8 W maximum power loss, panel thermal rise stays manageable — no forced cooling needed in a standard IP54 enclosure for a single breaker, but bank several in a row and you will want to check the aggregate dissipation against the enclosure's thermal budget. ## Panel fit and switchgear integration Dimensions: 130 mm height, 76.2 mm width (3-inch standard), 70 mm depth. That 3-inch wide footprint is the standard SENTRON 3VA fixed-pattern width — it drops into the same mounting cutout as the 3VA1 family. The integrated undervoltage release (UVR) is factory-installed — no field add-on module needed. ## Environmental range Operates from -25 °C to 70 °C ambient — the current derating above 55 °C is modest (62 A at 55 °C, 58 A at 70 °C). The 70 mm depth figure is the key dimension for panel layout — verify that the enclosure depth plus door clearance accommodates the breaker handle throw and cable exit. Lifecycle is current — no EOL notice, no phase-out. This is the active catalog number for a line-protection MCCB with UVR and auxiliary switches. No successor number exists because it is the current offering. For BOM continuity, this part is specified into new panels and replacement spares alike.","metaTitle":"Siemens 3VA1063-3ED36-0BH0 SENTRON MCCB, 63 A, 3-Pole, 70 mm","metaDescription":"Siemens 3VA1063-3ED36-0BH0 SENTRON molded case circuit breaker, 63 A at 40 °C, 3-pole, 75.6 kA at 240 V.
