The F&F CZF-334 rail-mounted relay monitors the voltage on each phase of a three-phase power supply and protects electric motors. It detects voltage loss on at least one phase, a drop below 320 V, a rise above 480 V, and phase imbalance. The adjustable imbalance threshold and delay time allow its operation to be tailored, while an LED indicates its operating status.
Once the fault has been corrected, the relay automatically reactivates. It uses True RMS technology and a microprocessor.
