Mikro's overcurrent protection delivers comprehensive protection schemes for low voltage applications. All Mikro's overcurrent units are microprocessor-based numerical relays and are housed in high-strength protective casing. The models in the range provide a wealth of options including programmable relay outputs to static, and digital display or dial activated.

Key Benefits

  • Accurate, reliable and more resistant to vibration and shock than traditional electromechanical relays
  • Current measurement based on fundamental frequency, prevents nuisance tripping
  • Digital display or dial activated for ease of use
  • Robust casing protects the unit from external interference
  • Complies with IEC 60255-26 standards

 

Applications

  • Feeder incoming protection
  • Outgoing protection
  • Busbar protection
