The device label lists Icu\/Ics values of 65\/30 kA at 400V, 50\/15 kA at 440V and 4\/2 kA at 690V, with a maximum back-up fuse of 160A gG at 400V and 125A gG at 440V and 690V. It is marked CAT. A, Uimp 6kV and 50\/60 Hz, and complies with IEC\/EN 60947-2 and IEC\/EN 60947-4-1. The unit is made in Germany by Siemens AG, Amberg, and carries CCC, KC and EAC marks. The label shows main terminals L1-T1, L2-T2, L3-T3 for conductors up to 35 mm² (50 mm² single conductor) and control terminals for auxiliary contacts. Motor protection circuit breakers of this type provide short-circuit and overload protection for three-phase motors, so this part is commonly sourced by panel builders, EPC contractors and MRO teams. WeSellStocks.co is a surplus and wholesale industrial supplier, offering the Siemens 3RV2031-4WA10 to procurement teams and distributors in the USA, the UAE and Worldwide.
