The K8AB-PM industrial series monitors overvoltages, undervoltages, phase sequence and phase loss for 3-phase, 3-wire or 4-wire power supplies, in one unit. This relay features a switch setting for 3-phase, 3-wire or 3-phase, 4-wire power supply.

• Worldwide power specifications supported by one unit
• Phase sequence, phase loss: operation reaction time 0.1s maximum
• Overvoltages or undervoltages: operation time setting from 0.1 to 30s
• Relay warning status can easily be monitored using the LED indicator
• Easy wiring with ferrules
