RN-101M
NOVATEK-ELECTRO
1 GENERAL APPLICATION
The RN-101M voltage protection relay is designed to disconnect (turn OFF) industrial or home-used
single-phase 240V/50Hz equipment with rated power up to 3.5 kW (16A) in case of inadmissible voltage
surges, with automatic turn ON function when the mains parameters return back to normal values after the
fault.
The RN-101M combines and comprises several devices in one compact case:
supply-line filter which protection of the connected power load from high-frequency and high-
voltage impulse faults.
current protection circuit breaker
The RN-101M displays the input RMS voltage value, the output relay status (closed/open) and the status
of the over-current protection circuit breaker.
Attention!
Do not use this device in inverter circuits.
