The Siemens 3VA1463-7GE42-0AA0 is a 4-pole IEC frame 630 circuit breaker with a breaking capacity class C rating of Icu=110kA at 415 V. The TM220 thermal-magnetic trip unit provides adjustable overload protection (Ir from 441 A to 630 A) and a fixed short-circuit pickup of 8 x In (5040 A), so you can coordinate selectively with downstream breakers on a distribution panel.
Deployment context
This breaker mounts in a standard IEC distribution panel or switchboard — the 4-pole configuration handles three-phase plus neutral, with 100% N conductor protection. The nut keeper kit simplifies panel wiring by retaining the terminal nuts during assembly, a small time-saver on a large build.
