Features of Phase-sequence phase-loss relay OMRON K8AB-PH1
Three-phase Phase-sequence Phase-loss
Relay Using Voltage Detection Method
Fixed phase Asymmetry monitoring
• 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.
