The box label describes the item in several languages as a semiconductor contactor and lists the order variant 1P3RF2450-1AC45+SG\/220905, a quantity of 1 and the manufacturer Siemens AG, Amberg. The unit label shows Ue 48-600V at 50\/60 Hz, 38A AC-51 at 40°C ambient, a rated motor output of 19.9 kW at 230V and 34.6 kW at 400V, Uimp 6 kV and compliance with IEC 60947-4-3. It is made in Germany and carries CE, UKCA, UL (Ind. Cont. Eq. 165C), CSA, RCM and EAC marks. The unit is mounted on a ribbed heatsink. Solid-state contactors of this type switch resistive and heating loads without mechanical wear, so this part is commonly sourced by panel builders, automation engineers and MRO teams. WeSellStocks.co is a surplus and wholesale industrial supplier, offering the Siemens 3RF2450-1AC45 to procurement teams, EPC contractors and distributors in the USA, the UAE and Worldwide.
