Fanox GL200 — Integral Motor Protection Relay for Large Motors

The Fanox GL200 is the high-current flagship of the GL Series, covering 3-phase motors from 60 to 200A directly — and extending to motors up to 630A via external current transformer (cable feed configuration). Designed for large industrial motors in the 37–110 kW range and beyond, the GL200 provides the full Fanox integral protection suite with Modbus RTU communication for critical process integration.

Full Integral Protection Suite

  • Thermal image memory — precise winding temperature model for high-inertia and high-duty cycle motors
  • Phase loss detection at reduced load — critical for large motors where single-phasing at low load is common
  • Phase imbalance and sequence protection
  • Underload / dry running detection — essential for large pumping and compression systems
  • Earth leakage protection
  • Overtemperature via PTC thermistor

High-Current Capability

Direct connection for motors up to 200A. External CT (cable feed) extends protection to motors drawing up to 630A — covering the largest industrial motors in plant and process environments.
