The circuit breakers and fuses protect against overload or short circuits.
The earth leakage protection device protects against currents flowing into materials.
Both cases may generate electrical arcs and create fires.
But without overcurrent or earth leakage current, some dangerous arcs, invisible to traditional protections, may also appear into cables or electrical connections.
These arcs are generated by loose contacts into connections, and into cables with damaged conductor or insulation. These arcs can become dangerous and create fires before any other type of protection detects them.
Arc Fault Detection Devices algorithms are deigned to discriminate dangerous arcs and trigger protection before any harm is done to the electrical installation.
