The Siemens 3VA1163-4GF42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker in the 3VA1 series, rated 63 A with a breaking capacity class S — Icu of 36 kA at 415 V.
Overload and short-circuit protection settings
The TM240 thermal-magnetic trip unit gives an adjustable overload protection range Ir = 44 A to 63 A, so you dial in the exact continuous current of the downstream load — a 50 A motor circuit or a 60 A feeder, for example. Short-circuit magnetic pickup Ii is adjustable from 5 to 10 times In (315 A to 630 A at the 63 A setting), letting you coordinate with downstream branch breakers or avoid nuisance trips on motor inrush.
