K8AB-PM1

Monitoring relay 22.5mm wide, simultanious monitoring of over voltage, under voltage phase sequence and loss in 3phase 3wire and 4 wire systems operating between 115 - 240 VAC K8AB-PM 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
