CKF-317 PHASE SEQUENCE AND FAILURE SENSOR 10A

The CKF-317 phase sequence and failure sensor provides effective protection for electric motors against the effects of voltage loss and voltage asymmetry between phases.

Application

The product is designed to protect motors powered from a three-phase network, preventing motor damage in the event of voltage loss in at least one phase. Additionally, it monitors the direction of motor rotation in case of phase change.
