RN-101M Single phase voltage monitoring relay with built-in electronic MCB (16A) is designed to de-energize an industrial/domestic appliance single phase 220 – 240V/50Hz load in case of inadmissible voltage variations in the mains with subsequent automatic re-energizing after the circuit parameters recovery.

Besides, the relay:

  • Protects the switched load against high-frequency and high voltage impulse interference
  • Limits load current up to 15A (load wattage of up to 3.5 kW)
  • Indicates the circuit RMS voltage

The device front panel features load status indicator (on/off) and three-digit, seven-segment display, which displays (depending on the device status):

  • Actual RMS voltage
  • Accurate value of the set-up parameter
  • Time remaining till automatic load re-closing
  • Emergency de-energizing the load (RMS voltage flashing)

The variable pot knobs on the front panel allow for setting:

  • The maximum allowable voltage tripping threshold
  • The minimum allowable voltage tripping threshold
  • Time (ON) delay for load re-closing after the circuit parameters recovery
