Description

Siemens 3TF4010-0B SICOP Power Contactor | Size 0, 9A, 4kW, 1NO (New Old Stock Unboxed)

This is a genuine Siemens 3TF4010-0B power contactor from the classic SICOP World Series line. First, this compact industrial switch handles a 9A load safely. Additionally, it works perfectly up to 4kW at 400V. Because this is a New Old Stock (Unboxed) item, it is completely unused. Consequently, it gives you a factory-fresh component at a reduced surplus price.
This model belongs to the popular SICOP 3TF40 range. In general, engineers use it to switch three-phase motors and small automation circuits. Furthermore, it features a built-in 1 NO auxiliary contact for extra control signals. It also comes with strong screw terminals and a highly compact Size 0 frame layout.
Since Siemens discontinued this original series, finding unused replacement parts can be tough. However, using this original stock unit makes your machinery repairs exceptionally fast. As a result, you do not have to waste time re-engineering your panels for newer generation models.
