The RN-113 1-ph voltage relay is designed to ensure the safe disconnection of industrial and domestic single-phase loads (220V and 50Hz) in case of unacceptable voltage fluctuations in the network. Additionally, the relay functionality provides automatic reconnection as soon as the network parameters are restored.
The RN-113 1-ph relay operates in 4 independent modes:
• voltage relay;
• maximum voltage relay;
• minimum voltage relay;
• time relay with turn-on delay function.
The front panel of the relay features a load indicator, as well as a 3-digit 7-segment display, which can indicate:
• current operating voltage data;
• exact value of the set parameter;
• time remaining until load reconnection;
• when the current voltage reading flashes — emergency load disconnection.
The front panel of the RN-113 1-ph relay also features potentiometer knobs that allow you to adjust:
• tripping at the maximum allowable voltage level;
• tripping at the minimum allowable voltage level;
• load turn-on delay once network parameters are restored.
