Measuring and Monitoring Relays

OMRON Measuring and Monitoring Relays are available from low to high voltages. They monitor the status of main power supply circuits to protect electrical circuits and manufacturing facilities from overcurrents, earth-faults, undervoltages, phase loss and other adverse conditions.

  Model No. Brief Description
K8AB Series Measuring and Monitoring Relays K8AB Series

Seven slim models featuring a variety of innovative new functions:
Single-phase power monitoring: Current relay, Voltage relay, Upper-/lower-limit voltage relays.
Three-phase power monitoring: Phase sequence relay, Voltage with phase loss relay, Voltage asymmetry relay, Voltage relay.
