  • Motor control circuits for small machinery
  • General automation and power distribution tasks

When it may not be suitable

This contactor is not intended for high-voltage industrial applications exceeding its rated current capacity. It should not be used in environments with extreme moisture, dust, or corrosive gases unless housed in an appropriate protective enclosure.

Key specifications

How to use

The F&F ST25-31 is designed for installation on a standard 35mm DIN rail within an electrical distribution cabinet. Ensure that the power supply is disconnected before beginning the installation. Connect the control circuit wires to the coil terminals and the load circuit wires to the corresponding NO and NC power terminals according to the wiring diagram provided on the device housing. Once installed, verify that all connections are secure and that the contactor operates correctly under load conditions.

What to consider before purchase

  • Verify that the 25A rated current is sufficient for your specific load requirements
  • Ensure the 3NO+1NC contact configuration matches your control logic
  • Confirm that there is adequate space on your DIN rail for the module
