Phase failure and phase asymmetry relay FF CKF-317 1P 10A 4 s 40–80 V
Summary description:
FF CKF-317 is a single-pole phase failure and phase asymmetry relay designed for supply protection and control. It monitors phase sequence, phase loss and voltage asymmetry within 40–80 V and trips a 10 A contact after a 4-second delay. Suited for motor and pump protection, control panels and industrial installations where phase monitoring prevents equipment damage and downtime.
