Order code K8AK-PH1 is a genuine Omron phase sequence/loss relay of the K8AK-PH range. Omron describes it as: Monitoring relay 22.5mm wide, simultanious monitoring of phase sequence and loss in 3phase 3wire systems, One DPDT.
Monitoring relays watch the supply or the load – phase sequence, phase loss, voltage or current – and trip an output before a motor or pump is damaged.

Compatibility and replacement
Use the complete order code K8AK-PH1 when ordering: in the Omron code the suffixes select output, connection, coil or supply voltage and cable length, so a part with a different suffix may not be a drop-in replacement.
If your old phase sequence/loss relay is discontinued or only partly readable, send us a photo of the label and we will confirm the current Omron equivalent before quoting.
