CZF-331 Phase Loss and Asymmetry Sensor 2X8A 2P 3M 2X400/230V+N AC
The phase loss sensor is designed to protect an electric motor powered from a three-phase network in cases of voltage loss in at least one phase or voltage asymmetry between phases, which threaten to damage the motor.
Application
This sensor, thanks to two separated contacts and control of phase loss and asymmetry, is an ideal solution for protecting electrical devices in harsh working conditions.
