The Siemens 3VA1163-3EF42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker from the 3VA1 series, rated for line protection with a TM240 thermal-magnetic trip unit. Its 63 A continuous rating (In) with overload protection adjustable from 44 A to 63 A (Ir) and short-circuit pickup from 5 to 10 times In (Ii) gives you a coordinated protection band for feeder or distribution circuits. The 25 kA Icu at 415 V (breaking capacity class N) means it can safely clear a bolted fault up to that level without upstream fuses needing to intervene — a key number for panel SCCR compliance.
