- Verified order-code-specific electrical and system details.
- Replacement requires complete installed-system matching.
Siemens 3TF5422-0XM0 is a heavy-duty three-pole contactor for switching qualified motors and other AC loads. Its complete order code identifies the 3TF54 frame, 2NO + 2NC auxiliary contacts and the -0XM0 AC coil execution for 220 V at 50 Hz or 264 V at 60 Hz. Replacement must preserve the motor duty, control voltage, auxiliary logic, overload protection, terminal arrangement and mechanical installation.
Before replacement, record the complete label, installed position, wiring, accessories and retained configuration. After installation, verify diagnostics and every affected function under an approved controlled procedure.
The Siemens 3TF5422-0XM0 250 A AC Contactor is listed as Obsolete / Discontinued by OEM. Current revision, availability and supplied scope are confirmed in the written quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 3TF54 frame is used for high-current three-phase loads. For 3TF5422-0XM0, verify 250 A AC-3 duty at 380 V and the documented 132 kW motor rating at 380/400 V against the installed motor, utilization category and switching frequency. The contactor rating does not replace overload and short-circuit protection coordination.
The 22 code identifies two normally open and two normally closed auxiliary contacts. The -0XM0 suffix identifies an AC coil for 220 V at 50 Hz and 264 V at 60 Hz. Confirm the actual nameplate, control transformer and frequency before energizing; a different suffix is not electrically interchangeable.
Before removal, label the line, load, coil and auxiliary conductors and record overload settings, interlocks and mechanical mounting. Isolate all power, use the approved Siemens instructions and terminal hardware, and maintain the original starter coordination. After installation, verify coil voltage, phase sequence, auxiliary feedback, interlocks and controlled opening and closing.
