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
