Siemens 3VA1 IEC frame 160, 4-pole circuit breaker, breaking capacity class N, Icu=25kA @ 415V, TM210 line protection, In=125A, Ir=125A fixed, Ii=10 x In.
The Siemens 3VA1112-3ED42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker from the 3VA1 series, rated at In=125A with a fixed overload protection setting (Ir=125A) and fixed short-circuit protection at Ii=10 x In.
The 3VA1 frame mounts on DIN rail in a standard panel enclosure. The nut keeper kit for DC Power OEM in China indicates this variant was kitted for a specific OEM assembly; the keeper secures the breaker's terminal nuts during transport and panel vibration.

The breaking capacity class N provides Icu=25kA at 415V, which is the maximum short-circuit current it can safely interrupt at that voltage.
It means the neutral pole is not switched — the breaker opens only the three phase conductors. This is typical for systems where the neutral is bonded to ground and must remain continuous.
