Siemens MFKE3 Contactor - Auxiliary Contact Block

The Siemens MFKE3 is an auxiliary contact block designed to be mounted onto Siemens contactors, typically from the 3RT series. It provides additional contacts (usually 2 NO + 2 NC) to expand the control circuitry of the main contactor, enabling more complex logic and signaling.

This auxiliary contact block is crucial for applications requiring feedback, interlocking, or additional control signals for motor starters and power contactors. It's widely used in control panels for machinery, building automation systems, and process control.
