Core features of C440 electronic motor protection relays

  • Electronics accurately identify excessive current or phase loss and react to conditions with greater speed, reliability and repeatability than traditional electromechanical devices
  • Integral ground fault protection supporting true simultaneous ground fault protection and communications – translates to reduced inventory, quicker installation time and a reduced physical footprint
  • Flexible communication with optional I/O enables easy integration into plant management systems for remote monitoring and control
  • Remote monitoring capabilities to discover changes in your system protects against unnecessary downtime
  • LED indicator provides predictive indication that allows users to determine the status of the overload as well as an impending trip to provide enhanced protection of your most important assets
  • Wide FLA adjustment (5:1) and selectable trip class improves return on investment by reducing inventory carrying costs
  • Patented thermal modeling design results in increased motor life
  • Voltage loss restart provides automatic revival after outages
