K8AB-PH

Phase-sequence Phase-loss Relay K8AB-PH CSM_K8AB-PH_DS_E_2_1 Three-phase Phase-sequence Phase-loss Relay Using Voltage Detection Method Prevents reverse motor rotation due to incorrect wiring. Distinguishes between positive phases, reversed phases, and phase loss when power is turned ON. Voltage detection method enables application for any load current. One SPDT output relay, 6 A at 250 VAC (resistive load). Output status can be monitored using LED indicator. Refer to Safety Precautions for the K8AB Series. Refer to page 5 for the Q&A section.
