The overload protection band (Ir) is adjustable from 44 A to 63 A; short-circuit pickup (Ii) is fixed at 10× In, so 630 A instantaneous. That's a standard motor-start or feeder-protection curve, not a selective (S) or instantaneous-only (M) variant. The 36 kA @ 415 V Icu tells you the breaker survives a single fault at that level and can be reclosed — it's not a one-shot fuse. The N conductor is unprotected on this variant (the neutral pole is not switched), so it's intended for 3-phase + ground applications where the neutral carries only unbalanced load, not fault current. The 'nut keeper kit for DC Power OEM in China' note in the description flags that this specific Z-code variant includes hardware for DC-side mounting — likely for a solar combiner or battery-string application where the breaker is installed on a busbar rather than a DIN rail. The 3VA1 frame 160 mounts on a backplate or DIN rail via the standard Siemens clip system. Four poles at 63 A means the breaker occupies roughly 144 mm of panel width (36 mm per pole). The TM220 thermal-magnetic trip is field-adjustable for Ir, but Ii is fixed — no need to fiddle with a secondary dial for short-circuit pickup. The load-side lugs accept copper or aluminum conductors up to 50 mm². For the DC Power OEM variant, the included nut keeper kit secures the breaker to a busbar without loose hardware falling into the enclosure during installation.","metaTitle":"Siemens 3VA1163-4EE42-0AA0-ZD00 Circuit Breaker, 63A, 36kA @","metaDescription":"Siemens 3VA1163-4EE42-0AA0-ZD00 IEC frame 160 circuit breaker, 63A, 36kA breaking capacity @ 415V.
