The current signal is converted into a voltage and compared with an internally pre-adjusted reference voltage proportional to the network voltage, according to the selected sensitivity (sensitivity is the insulation resistance value of a line that causes the relay to act, considering the other line infinite). If the measured value is below the adjusted level, the red indicator LED will light up and the output relay will switch its contacts, remaining in this condition until the system returns to normal (fault extinction).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eTechnical Characteristics:\u003c\/p\u003e\n\u003cp\u003eRated Voltage: 125VDC\u003c\/p\u003e\n\u003cp\u003eAuxiliary Power Supply: 220V\/60Hz\u003c\/p\u003e\n\u003cp\u003eContact Capacity: 10A (250V\/60Hz)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eDate: 08\/05\/2024\u003c\/p\u003e\n\u003cp\u003eWeight: 0.320Kg\u003c\/p\u003e\n\u003cp\u003eMeasurements: 10x15x24\u003c\/p\u003e\n\u003cp\u003eLocator: B2P2B\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eDear customers, if the material is intended for resale, the ST (Tax Substitution) value may apply.
