What this wiring harness connects
The Siemens 3RW3986-7DC84 is a TSE wiring harness designed for the SIKOSTART 3RW3486-0DC34 soft starter, supporting a supply voltage range of 200-460 V AC. This is the dedicated wiring set that connects the soft starter to the line and motor — not the starter itself, but the cabling kit specified for that exact frame.
Integration note
The TSE wiring harness mates directly to the SIKOSTART 3RW3486-0DC34 soft starter terminals. Verify the 200-460 V AC range matches your line voltage before pulling cable. Rated operating range covered in the spec table. Off-state leakage stays under the listed maximum at 25 °C; derate per the thermal curve above 40 °C. Storage temperature exceeds operating range — handling, not running, is what that limit governs.
