... Note: 1. Motor load phase loss cannot be detected. To detect motor load phase loss, use the K8AB-PM or K8AB-PA. 2. The K8AB-PH output relay is normally operative and L3 function both as the power supply terminals and as input terminals. If the voltage drops below the minimum input voltage (60%), then the Relay will not operate due to an undervoltage ...
