Overview
The Siemens 3RA1954-2A Mechanical Interlock is a crucial safety component designed for use with the SIRIUS family of power contactors. This high-quality accessory ensures that in a reversing or change-over application, only one contactor can be closed at a time, providing essential mechanical safety against simultaneous operation (short circuit/fault condition). It is specifically engineered for the larger frame sizes, offering a perfect fit and reliable performance for SIRIUS contactor sizes S6, S10, and S12 from the 3RT10, 3RT12, and 3RT14 series.
