More Information

Overview Manuals Main Circuit Coil Matching Auxiliary Logic Starter Coordination

Features:

  • Switches a three-phase motor circuit through three AC-3 main poles.
  • Uses a 220 V 50 Hz or 264 V 60 Hz conventional AC operating coil.
  • Provides two normally open and two normally closed auxiliary contacts for control logic.
Match 3TF4522-0XM0 by complete order number, coil data, pole arrangement, and auxiliary-contact allocation before replacing a similar 3TF contactor.

Transfer main, coil, and auxiliary wiring by terminal designation and retain the overload relay or branch protection specified for the motor circuit.

Commission the coil command, mechanical pickup, contact continuity, and overload trip path as separate checks.

The Siemens 3TF4522-0XM0 3TF45 AC-3 Power Contactor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Tracing motor power through the three contact poles

  • Line side: The three incoming phases land on the line terminals.
  • Load side: The matching load terminals continue to the motor branch.
  • Coil action: Energizing the coil closes all three main poles together.
  • AC-3 duty: The 38 A rating applies to the documented motor-switching category.

Choosing control voltage by both frequency and value

  • 50 Hz supply: The coil uses 220 V AC on a 50 Hz control circuit.
  • 60 Hz supply: The same coil marking permits 264 V AC at 60 Hz.
  • Undervoltage: Low control voltage can prevent full armature closure.
  • Overvoltage: Incorrect control voltage can overheat the coil.

Using the 2NO+2NC contacts for feedback and interlocking

  • NO feedback: A normally open contact closes when the contactor operates.
  • NC interlock: A normally closed contact opens as the main poles close.
  • State relationship: Auxiliary motion follows the same contactor mechanism.
  • Separate duty: Control contacts do not carry the three-phase motor current.

Combining switching with separate protective devices

  • Overload relay: The overload device monitors sustained motor overcurrent.
  • Short-circuit device: A fuse or breaker interrupts high fault current.
  • Contactor role: The 3TF unit performs commanded switching.
  • Selection check: Motor rating and protective coordination are verified as one starter branch.
Description
Siemens 3TF4522-0XM0 is a 3TF45 size S2 electromagnetic contactor that switches a three-phase AC motor circuit. Its three main poles carry the power path, while the coil turns the mechanical contact system on or off from the control circuit.

The coil of 3TF4522-0XM0 is rated for 220 V AC at 50 Hz and 264 V AC at 60 Hz. The control transformer or supply must therefore match both the voltage and frequency marking rather than only the nominal voltage family.

Two normally open and two normally closed auxiliary contacts on 3TF4522-0XM0 follow the main contactor mechanism. They can report the operated state or form interlocks, but their control duty is separate from the 38 A AC-3 main circuit.

When 3TF4522-0XM0 is used in a motor starter, short-circuit protection and overload protection remain separate coordinated devices. The contactor supplies the switching function and must be selected together with those protective components for the motor duty.

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 does Siemens 3TF4522-0XM0 chatter instead of closing firmly?
Check whether the coil of Siemens 3TF4522-0XM0 is receiving the correct voltage for the actual 50 Hz or 60 Hz supply.
Can the auxiliary contacts of 3TF4522-0XM0 switch the motor current?
No. The 2NO+2NC auxiliary contacts of 3TF4522-0XM0 serve control and feedback circuits, not the main motor path.
What should be checked if one motor phase is missing through Siemens 3TF4522-0XM0?
With power isolated, inspect the corresponding main contacts, terminals and conductors on Siemens 3TF4522-0XM0.
Does 3TF4522-0XM0 replace an overload relay?
No. 3TF4522-0XM0 performs switching; a coordinated overload relay provides sustained motor-overload protection.
Which coil supply belongs to Siemens 3TF4522-0XM0?
Siemens 3TF4522-0XM0 uses 220 V AC at 50 Hz or 264 V AC at 60 Hz.
How can 3TF4522-0XM0 provide an electrical interlock?
Use an appropriate normally closed auxiliary contact of 3TF4522-0XM0 in the opposing contactor control circuit.
