The Siemens 3VA2463-7HN32-0BA0 is a SENTRON molded case circuit breaker (MCCB) rated for 630 A continuous current at 40 °C, with a 3-pole configuration and an ETU350 electronic trip unit. The interrupting ratings are serious: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V.
The 630 A rating at 40 °C is the headline number, but it derates as ambient temperature climbs: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. That matters when sizing for a non-overload trip point. Power loss is 164.5 W maximum, which adds to panel heat load; factor that into your enclosure cooling calc.
Integration notes
The breaker measures 138 mm wide, 248 mm high, and 110 mm deep. An undervoltage release (UVR) is built in, with the release design specified as undervoltage release (UVR) type. No auxiliary contact version is included, so if you need status feedback to a PLC, you'll add an external auxiliary contact block. No communication function, no phase failure detection, no ground fault monitoring — this is a straightforward line-protection breaker, not a smart metering device.
