Reversing contactor for motor direction control
The 3RA9012-5AK11: The reversing configuration lets you swap motor rotation direction without an external interlock — the mechanical and electrical interlocking is built into the contactor assembly. The 1NO-1NC aux contacts per side give you feedback signals for the PLC or status lamps without adding a separate aux block.
Because the lifecycle stage is current, this part is sourced through standard Siemens distribution channels.
