The RN-113 voltage monitoring relay is designed to de-energize an industrial/appliance single-phase 220V/50Hz load in case of inadmissible voltage variations in the mains with subsequent automatic re-energizing after the circuit parameters recovery.
The load is connected to the relay either directly via relay terminals or through a magnetic starter, depending on the wattage.
The relay can operate in four independent modes:
- voltage monitoring relay;
- minimum voltage monitoring relay;
- maximum voltage monitoring relay;
- time relay with a restart delay.
