Compact monitoring relays – Quick and easy wiring without tools

With the compact EMD-BL monitoring relays, you can monitor important system parameters in your application. Detect critical errors early, report them, or shut system components off selectively.

You can choose from four device types:

  • Current monitoring, 1-phase: overcurrent, undercurrent, window
  • Voltage monitoring, 1-phase: undervoltage, window
  • Voltage monitoring, 3-phase: window, phase sequence
  • Phase monitoring: phase sequence, phase failure, asymmetry
