Product details

Overview

The 3RB2956-2TH2 is a Siemens current transformer rated 20-200 A, designed for use with 3RB22/23/24 Size S6 overload relays. It mounts on the contactor or as a stand-alone unit with busbar connection. Siemens has phased this part out as of 2023-10-01.

Siemens lists the 3RB2956-2TH2 as phase-out with a discontinuation date of 2023-10-01. No official successor is listed. For a line-down or BOM-fill need, sourcing is limited to surplus and broker channels; an RFQ is the fastest path to confirm available quantity and lead time.
