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.
