The F&F CKF-316-TRMS DIN-rail relay is a microprocessor-based phase sequence and phase loss monitoring relay for three-phase networks. It checks the phase sequence, detects voltage loss on any phase, and monitors voltage asymmetry.
It mounts on a DIN rail and features an LED indicator, screw terminals, and a 4-second switch-off delay.
