Digital phase sequence and phase failure sensor, 16A 2-mod. time and threshold setting CKM-10 EXT10000266

The CKM-10 phase sequence sensor is used to protect devices powered from a three-phase network (e.g. motors) against damage in the event of a phase voltage failure, phase voltage asymmetry or incorrect phase sequence. The asymmetry threshold value can be set by the user using a potentiometer. The sensor also protects against a symmetrical voltage drop by switching off the relay if the voltage on any phase drops below 150 V (regardless of the asymmetry level). The device is powered from any phase, which means that the presence of voltage on one phase is enough for it to be fully functional. Adjustable switch-off delay and voltage hysteresis make the sensor resistant to short-term voltage fluctuations.
