CZF-B Box F&F phase loss sensor

Product description

The phase loss sensor is a device that monitors the phase voltage of motors or other equipment. With its help, you can try to run them in open phase conditions or in single-phase mode, thus eliminating motor burnouts. It works on the principle of phase voltage, which occurs in a three-phase system. It also protects against phase loss.

It works on the principle of protecting the motor from possible voltages in power cables. It detects the operating power of the equipment in question, when there is a phase loss in any of the three phase modes, the wire loses or recharges power. A time delay of about 1.5 seconds has been introduced to eliminate the possibility of nuisance tripping.
