MM35-DIN Series for High Power Inrush Current Applications

Ametherm thermistor Inrush Current Limiters have become the industry standard to reduce inrush current across the electronics industry. With the development of Ametherm’s MM35-DIN Series, Inrush Current Limiters can now take on industrial-strength high power inrush current inrush for high power industrial applications.

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.
