That matters when you need selectivity downstream or want to dial in the protection for a specific cable run. ## Interrupting capacity — what those kA numbers mean for your panel At 240 V this MCCB can interrupt 330 kA — that's a massive fault current, typical for a main breaker right behind a large transformer. At 415 V and 440 V it still handles 242 kA, and at 500 V it's 187 kA. The 690 V rating drops to 5.25 kA, which is still adequate for most 690 V motor circuits but not for high-fault service at that voltage. Front IP40 protection means it's fine inside a closed panel; no special gasketing needed for the enclosure door cutout. ## Auxiliary contacts and accessories Comes with 2 auxiliary switches plus a trip alarm switch (HP version) — that's enough to send a remote status signal to a PLC or SCADA for both breaker position and trip condition.","metaTitle":"Siemens 3VA2163-7HN32-0AJ0 SENTRON MCCB, 63 A, 3-Pole, ETU35","metaDescription":"Siemens 3VA2163-7HN32-0AJ0 SENTRON molded case circuit breaker, 63 A rated continuous current, 3-pole, ETU350 electronic trip, 330 kA at 240 V.
