The Siemens 3VA1463-4GF42-0AF0 is a 4-pole IEC frame 630 circuit breaker from the 3VA1 series, rated for line protection with a TM240 thermal-magnetic trip unit.
Overload and short-circuit protection settings
The thermal overload protection Ir is adjustable from 440 A to 630 A, matching the full In=630 A rating. The magnetic short-circuit pickup Ii is set at 4 to 8 times In, so on a 630 A frame that gives a pickup range of 2520 A to 5040 A — wide enough to ride through motor inrush on a large pump or compressor feeder while still clearing a bolted fault fast.
Integrated accessories
That means you get a position-feedback contact for the panel PLC and a separate alarm contact that changes state only when the breaker trips on fault — no need to order and mount them separately in the field.
