Product Positioning

The 3RA2922-2H is a side-mounted mechanical interlock in the Siemens SIRIUS modular system, designed for mechanical interlocking between S0-size contactors. By mounting two 3RT202 or 3RT232 contactors side-by-side using the interlock, it ensures that they will not engage simultaneously, commonly found in forward and reverse motor starting circuits. Kenxin Motors is an authorized Siemens distributor, providing genuine original parts.
