The Siemens 3VA1063-4ED42-0AF0 is a 4-pole IEC molded-case circuit breaker in the 3VA1 frame, rated 63 A continuous with a fixed thermal-magnetic TM210 trip unit. The TM210 overload is fixed at Ir=63 A, and the short-circuit pickup is fixed at Ii=10 × In, so this is a straight swap-in replacement for a line-up that already expects those settings; no adjustment dials to verify.
The included nut keeper kit secures the breaker to the busbar assembly without the nuts spinning during torque-down — a detail that saves time on a panel-build line. The factory-fitted auxiliary switch (HQ) and trip alarm switch (HQ) give remote status indication without additional wiring labor.
