Description
With fixed actuation threshold voltage asymmetry.
Three phase and sequence monitor is designed to protect tree phase electric motors against voltage drop in at least one phase or voltage asymmetry between phases, which could damage the motor, with additional protection of motor rotation direction in case of phase change before the monitor.
