The 121 kA breaking capacity at 240 V and 75.6 kA at 415 V means it can safely interrupt high fault currents without upstream cascading, which matters when you are coordinating selectivity downstream of a transformer or large feeder. At 690 V the interrupt rating drops to 11.9 kA — still serviceable for most 690 V industrial loads, but verify the available fault current at that voltage level. The 630 A continuous rating holds flat through 50 °C; above that it derates to 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C. If your enclosure runs hot, plan the derate curve into the BOM. The breaker measures 184 mm wide, 248 mm high, and 110 mm deep — a standard MCCB footprint for 630 A frames. Front protection is IP40, meaning no splash or tool entry from the front face, but the rear and sides are open for panel-mount busbar connection. Rated insulation voltage is 800 V, so it suits 400 V and 690 V distribution systems within the interrupt ratings listed. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.","metaTitle":"Siemens SENTRON 3VA1463-4EF42-0AA0 MCCB, 630 A, 4-Pole, 121","metaDescription":"Siemens SENTRON 3VA1463-4EF42-0AA0 molded case circuit breaker, 630 A rated at 40 °C, 4 poles, breaking capacity 121 kA at 240 V.
