High Power Inrush Current Deserves Industrial Strength Inrush Current Protection

With continuous current ratings from 50A to 80A at 680V RMS and energy to 1,200 joules, the Ametherm MM35-DIN Series of Inrush Current Limiters can handle the high power levels found in the industrial environment.

Benefits of Employing the MM35-DIN Series

 

 

 

 

 

 

The MM35-DIN Series offer:

  • Higher energy ratings.
  • Ideal for power distribution.
  • Higher continuous current ratings.
  • Ideal for systems that are typically powered on once daily.
  • Single Part Solution. No need for additional by-pass circuitry.

Single and Three Phase Applications Include:

  • AC Motors.
  • Transformers.
  • Power Supply/Inverters.
  • Refer to the Maximum Power Ratings Chart for more applications.
