Breaking capacity hits 330 kA at 240 V AC and 242 kA at 415/440 V, with 52.5 kA at 690 V — high enough for most industrial fault-current scenarios without needing a current-limiting upstream device. ## Panel fit and mounting constraints Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard SENTRON 3VA frame size for 500 A. Front IP40 protection is sufficient for clean indoor panel environments.","metaTitle":"Siemens 3VA2450-7MN32-0HA0 SENTRON MCCB, 500 A, 330 kA","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0HA0 molded case circuit breaker, 500 A rated continuous current, 330 kA breaking capacity at 240 V.
