Fanox GL16 — Integral Motor Protection Relay

The Fanox GL16 is the entry point to Fanox's advanced GL Series — a comprehensive motor protection platform that integrates protection, control, monitoring, and communication in a single DIN rail device. Where the C Series provides essential protection, the GL Series provides integral protection against every major failure mode of a 3-phase motor.

Complete Protection in One Device

  • Overload + thermal image memory — same precise thermal simulation as C Series
  • Phase loss detection at reduced load
  • Phase imbalance and sequence protection
  • Underload / dry running detection — by undercurrent (I<): critical for pumps, compressors, and fans that can be damaged when running without fluid or load
  • Earth leakage protection — detects current flowing to ground before insulation failure causes motor damage or safety hazard
  • Overtemperature protection — via external PTC thermistor input (sensor sold separately)

Monitoring & Communication

  • Real-time current measurement display
  • RS-485 Modbus RTU communication — enables remote monitoring and SCADA integration
  • Trip cause indication and logging
