Phase sequence and phase loss sensor CKF-317 contacts: 1P, I = 10A, adjustable threshold: 165-180V, 1 module

CKF-317 sequence and phase loss relay.
Application:
designed to protect electric motors supplied from a three-phase network in the event of voltage failure in at least one phase or voltage asymmetry between phases, which may damage the motor, and to protect the direction of rotation of the motor in the event of a phase change in front of the sensor
