The voltage-frequency-relay 1P(Single Phase) monitors voltage and frequency in one Phase networks with neutral and switches off rapidly when required.
For safe running of electrical devices, special protections that keep a continuous watch on supply conditions are very essentials.
'PROTONs VFR 1P' offer following protections along with 3 digit display showing R-N(L-N) voltage and frequency in scanning mode with precise accuracy. LOW/HIGH voltage and frequency(settable) tripping to ensure trouble free running of Loads.
