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.<\/p>\n<h3>Application<\/h3>\n<p>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
