Product Overview
Siemens 3VA2063-6KQ46-0AA0 is a 4-pole molded-case circuit breaker from the 3VA2 IEC Frame 100 family. It provides overload (Ir adjustable 25 A…63 A), short-circuit (Isd = 0.6…10× In; Ii = 1.5…12× In), neutral conductor protection (adjustable up to 160 %), and ground-fault protection (0.25…1× In, switchable). Rated for up to 85 kA breaking capacity at 415 V, it is used for motor and line protection in industrial distribution panels where high breaking capacity and adjustable protection functions are required. Part number: 3VA2063-6KQ46-0AA0.
