RMT-101 current overload/over current relay is used for load rejection in case the current exceeds the set value between 0 and 100 amperes (settable).

The device can be used in the following capacities :

  • Digital ammeter
  • Current consumption limiting relay
  • Priority load selection relay

LEDs on the front panel of the relay indicate :

  • Load state (on/off)
  • Exceeding the maximum allowed load current threshold

Depending on the work mode, the three digit seven-segment indicator indicates:

  • Actual load current value
  • Maximum current value after the last reset
  • Value of the parameter being set
  • Time remaining until load activation or rejection
  • Presence of a reclosing blockage

Regulating potentiometers allow the user to set the following values:

  • Maximum allowed load current value threshold
  • Time for load rejection in case of exceeding
  • Maximum allowed load current threshold
  • Time delay before load activation after the current returns to the allowed level
