The Siemens 3VA4170-5ED34-3AA0 is a 3-pole molded case circuit breaker from the 3VA4 family, Frame 125, with a 70 A fixed thermal-magnetic trip unit (TM210). The overload protection (Ir) is permanently set at 70 A, and the instantaneous short-circuit pickup (Ii) is fixed at 10 × In (700 A), so it's a dedicated line-protection device, not field-adjustable for motor or generator applications.
