RMT-101

Relay control the maximum current.

RMT-101 designed to permanent control of active value current of single-phase load in 0 to 100A range,and to turn OFF it in case of excess of user adjusted maximum allowed load current (with independent timelag) with preset cut-OFF time and subsequent automatic insertion with preset turn-ON time or with block ofreclosing.Current sitting, reaction time of relay and autoreclosing time are adjusted by user using potentiometers onthe front panel of RMT-101. Measurement is carried out by built-in current sensor without break of electrical circuit.

RMT-101 can be used as:

• digital ammeter;
  
• limit relay input current;
  
• selection relay (to select of priority load).
  

In RMT-101 for current measuring it is used Built-in current transformer. RMT-101 allows controllingcurrent values and condition of load per LED indicators on the front panel.
