Model: MML1501 - Earth Fault Impedance Module
MML1501 provides a normalised earth fault leakage current return path in IT-networks.
The DIN-rail mounted MML1501 is used in non-grounded (isolated) AC supply systems, where loads/branches are to be selectively earth fault-monitored.
By providing a normalised earth fault leakage current return path, MML1501 improves accuracy and sensitivity of a earth fault monitoring system.
MML1501 is connected from each line voltage (R/S/T) to protective earth (PE).
Current load is depending of harmonic frequencies.
