Siemens SENTRON 3VA1463-7EE42-0AA0 — 630 A MCCB, 4-Pole, TM220 Release
Breaking capacity reaches 440 kA at 240 V, 242 kA at 415 V, and 154 kA at 500 V, dropping to 17 kA at 690 V — numbers that tell you this breaker is built for high-available-fault-current installations, typically close to a transformer or in a main switchboard. The 630 A continuous rating holds flat from 40 °C to 50 °C, then derates to 583 A at 70 °C; if your panel ambient runs hot, that derating curve (–) is the one to use for sizing.
The breaker measures 184 mm wide, 248 mm high, and 110 mm deep — a 4-pole frame that fits standard Siemens SENTRON mounting bases and switchboard cubicles. Front IP40 protection means it is suited for indoor panel installation where dust ingress is limited; no washdown or outdoor rating is claimed. No communication function or voltage trip indicator is built in — this is a plain thermal-magnetic MCCB. For remote trip indication or energy metering, add an external module.
