3-phase sequence, phase loss relay

The K8DS-PH1 is a monitoring relay designed at only 17.5 mm wide with simplified functions for 3-phase 3 wire supplies. It simultaneously monitors phase sequence and phase loss during start up as well as phase loss during operation. The output relay releases when alarm conditions are detected, and the warning status can easily be monitored using the LED indicator.

• Monitors phase sequence and phase-loss simultaneously
• Measuring range: 200 to 480 VAC
• Power supply voltage is the same as measuring voltage
• Operation reaction time: 0.1 s maximum
