The F&F CKF-B-TRMS DIN-rail relay protects electric motors powered by a three-phase supply. It monitors the true RMS voltage using TrueRMS technology, voltage loss on at least one phase, and phase imbalance. It prevents the motor from starting if the phase sequence changes.

  • Type: Phase-sequence and phase-loss relay
  • Supply voltage: 3 400 V + N
  • Maximum load...
