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.

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.
