Phase-sequence Phase-loss Relay
K8AB-PH
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.
