Reduce Incident Energy With SEL motorMAX High-Speed Arc-Flash Protection

SEL motorMAX is SEL’s smart motor control system for low-voltage motor control centers (MCCs). This scalable system includes protective relays, managed network switches, real-time automation controllers, precise time sources, and human-machine interfaces (HMIs) for local and remote visualization and control. Every SEL motorMAX solution is shipped with SEL high-speed arc-flash detection (AFD) and mitigation technology.

Features

  • SEL AFD and mitigation technology.
  • Standardized factory test report and system documentation.
  • Time-synchronized Sequence of Events (SOE), event oscillography, and motor start reports.
  • Advanced motor protection with patented thermal models for both rotor and stator.
  • Remote HMI monitoring and control.

 

Benefits

  • Reduce MCC costs by eliminating programmable logic controllers, unnecessary wiring, and interposing relays.
  • Identify operating conditions, trends, and running alarm conditions at a glance.
  • Improve work environment safety by reducing the incident energy of arcing faults.
  • Reduce the total cost of ownership with a fully tested, preconfigured motorMAX system.
  • Depend on the quality of SEL products—made in the USA.
