What this kit fits and why it matters
The 3RA9011-3AY25 is a Siemens kit specifically listed for the Albrecht DMU 160 P/MILL+TNC INDEX A13 machine — not a generic contactor or starter accessory, but a machine-specific service kit. If you are maintaining or repairing a DMU 160 with the TNC INDEX A13 control, this is the kit that matches the OEM bill of materials — no adapter plate or wiring rework needed.
For a turnaround or planned outage, this kit lands before the window — quoted to order against the BOM quantity, with availability confirmed at RFQ.
