Siemens SENTRON 3VA1463-7EE42-0AA0 — 630 A MCCB, 4-Pole, TM220 Release
The Siemens SENTRON 3VA1463-7EE42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated 630 A at 40 °C, designed for line protection in industrial distribution panels. Its TM220 thermal-magnetic release provides fixed overload and short-circuit protection without an undervoltage release or ground-fault monitoring — a straightforward choice for main feeder or large subfeed applications where selectivity and high fault current handling are the priority. 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.
Integration and Mounting
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.
