Fanox CBT – Three-Phase Pump Protection Panel (Cos φ)

The Fanox CBT is a complete 3-phase pump protection and control panel built around the Fanox PF-R relay. It monitors the power factor (cos φ) of the motor to detect dry running: when the pump empties and runs dry, cos φ falls sharply and the panel shuts down the pump automatically — protecting against costly dry-run damage without any float switches or level sensors.

  • Complete 3-phase pump protection and control panel
  • Integrated Fanox PF-R relay monitoring cos φ across all phases
  • Dry-running detection without level sensors or float switches
  • Automatic shutdown when cos φ falls below the preset value
  • Automatic reconnection after fault — no on-site reset required
  • Thermal-image protection for complete heat cycle control
  • Phase failure, phase imbalance, and phase inversion protection
  • Easy retrofit — fits existing pump installations without downtime
