Residual Current Device RCD-100 4P 63A Idn-30mA type AC CONTACTOR 7000555

• PURPOSE Mechanical switching device designed to connect, conduct, and disconnect currents under normal operating conditions, as well as to open contacts in case the differential current reaches a specified value under certain conditions • FIELD OF APPLICATION Used for installation in offices, retail, warehouses, and residential premises. • PRINCIPLE OF OPERATION When a leakage current occurs (human contact with a phase conductor, or a decrease in the insulation resistance of a cable line), the vector sum of the currents flowing through the RCD will not be equal to 0, as a leakage current appears that flows only through the phase conductor; a voltage proportional to the leakage current will be induced in the secondary winding of the transformer, and if a certain threshold is exceeded, the device will trip and disconnect the protected circuit. • ADDITIONAL ACCESSORIES OR ACCESSORIES The standard kit includes the product itself
