More Information

Overview Manuals Main Circuit Coil Control Auxiliary Paths Selection Check

Features:

  • Switches three AC power poles between L1/L2/L3 and T1/T2/T3.
  • Carries a 250 A AC-3 rating at 380 V for a 132 kW motor circuit.
  • Uses a 220 V 50 Hz / 264 V 60 Hz AC coil with 2NO+2NC auxiliary contacts.
Siemens 3TF5422-0XM0 separates the low-power coil command from the three high-current AC power paths.

The synchronized main contacts route all three phases, while the four auxiliary contacts provide independent interlock and indication circuits.

The complete suffix must be retained because the coil voltage and contact arrangement are part of the exact catalog identity.

The Siemens 3TF5422-0XM0 3-Pole AC Power Contactor may still be available through Apter Power after OEM discontinuation.
Siemens 3TF5422-0XM0 3-Pole AC Power Contactor Manuals,Datasheets,LinkImportant 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.

Three synchronized power paths

  • Incoming phases: 1/L1, 3/L2, and 5/L3 receive the three supply conductors.
  • Outgoing phases: 2/T1, 4/T2, and 6/T3 connect to the controlled load.
  • Contact action: The three normally open main poles close together with coil operation.
  • AC-3 duty: The exact contactor carries 250 A at 380 V in AC-3 service.

Frequency-dependent coil supply

  • At 50 Hz: The documented coil voltage is 220 V AC.
  • At 60 Hz: The documented coil voltage is 264 V AC.
  • Control boundary: The coil command remains separate from the three motor-current paths.
  • Suffix check: The 0XM0 suffix must match the installed coil configuration.

Interlock and indication contacts

  • Normally open contacts: Two NO auxiliary paths close with contactor operation.
  • Normally closed contacts: Two NC auxiliary paths open with contactor operation.
  • Circuit role: Auxiliary contacts serve status and interlock circuits.
  • Load separation: The auxiliary set does not carry the 250 A main-circuit current.

Identity and duty checks before installation

  • Catalog number: Confirm the complete 3TF5422-0XM0 model.
  • Motor duty: Match the 250 A AC-3 and 132 kW ratings to the feeder.
  • Coil source: Verify the actual frequency before applying the documented coil voltage.
  • Terminal routing: Keep each L1/L2/L3 conductor paired with its T1/T2/T3 load path.
Description
Siemens 3TF5422-0XM0 is a three-pole AC power contactor in the 3TF54 family. Its main contacts connect line terminals L1, L2, and L3 to load terminals T1, T2, and T3 so a separate control circuit can switch a high-current motor feeder.

The main circuit of 3TF5422-0XM0 is rated 250 A in AC-3 service at 380 V, corresponding to 132 kW at 380/400 V in the Siemens 3TF54 certification data. The three normally open power paths close together when the contactor coil is energized.

Control power for 3TF5422-0XM0 is specified as 220 V AC at 50 Hz or 264 V AC at 60 Hz. Two normally open and two normally closed auxiliary contacts provide separate status or interlock paths without carrying the three-phase motor current.

Technical notes
Siemens 3TF5422-0XM0 requires a 220 V AC 50 Hz or 264 V AC 60 Hz coil supply; the two frequencies must not be treated as the same voltage setting.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why might the coil on Siemens 3TF5422-0XM0 fail to pull in?
Check whether Siemens 3TF5422-0XM0 receives 220 V AC at 50 Hz or 264 V AC at 60 Hz; the permitted coil voltage changes with frequency.
Which terminals carry the three phases through Siemens 3TF5422-0XM0?
On Siemens 3TF5422-0XM0, the incoming phases connect to 1/L1, 3/L2, and 5/L3, while 2/T1, 4/T2, and 6/T3 feed the load.
How should the auxiliary contacts on Siemens 3TF5422-0XM0 be used?
The 2NO+2NC auxiliary set on Siemens 3TF5422-0XM0 is intended for interlock or indication circuits rather than the 250 A motor-current path.
What motor duty is documented for Siemens 3TF5422-0XM0?
Siemens 3TF5422-0XM0 is documented for 250 A AC-3 service at 380 V, corresponding to 132 kW at 380/400 V.
Why must the full suffix be retained when ordering Siemens 3TF5422-0XM0?
The 0XM0 suffix of Siemens 3TF5422-0XM0 identifies the AC-operated coil configuration, including its 50/60 Hz voltage pair.
What should be checked if one phase is missing after Siemens 3TF5422-0XM0 closes?
Inspect the matching L-to-T path and its conductor on Siemens 3TF5422-0XM0, because all three main poles should close with the same coil operation.
