Siemens 3VA1 IEC frame 160, 3-pole MCCB, 25A, breaking capacity class N, Icu=25kA @ 415V, TM210 thermal-magnetic trip, nut keeper kit for DC Power OEM in China.
The TM210 trip unit provides fixed thermal-magnetic overload protection (Ir = 25 A fixed) and short-circuit pickup set at 12.8 × In, so it clears bolted faults fast without nuisance tripping on motor inrush.
The nut keeper kit (included on this variant) prevents hardware loss during assembly — a small detail that saves time on the line for OEMs building panels in volume.
It is a 3-pole MCCB rated 25 A, with a breaking capacity of 25 kA at 415 V (class N). The TM210 trip unit has fixed overload protection at Ir = 25 A and fixed short-circuit protection set at Ii = 12.8 × In.
