The interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. For a line protection breaker that cycles infrequently (a few times a year for testing), that is ample; for a switching duty cycling daily, it is not the right part.","metaTitle":"Siemens 3VA1063-4ED32-0KH0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1063-4ED32-0KH0 molded case circuit breaker, 3-pole, 63 A rated, 121 kA at 240 V.
