3-phase sequence, phase-loss relay

K8AB-PH simultaneously monitors phase sequence and phase loss for 3-phase 3-wire power supplies. The relay warning status can easily be monitored using the LED indicator. Suitable for industrial facilities and equipment.

• 3-phase sequence, phase-loss relay
• Monitors both functions at once
• Measuring range: 200 to 500VAC
• Power supply voltage is the same as measuring voltage
• Operation reaction time: 0.1s maximum
