Overview
The iEF-AFD Fault Arc Detector can detect dangerous fault arcs caused by cable aging or loose
connections, which may easily trigger fires. This product is suitable for situations that can cause
electrical fires, including:
Parallel Arcs: Occur when insulation damage between two live conductors results in a resistive short
circuit. Because the fault current is very small, circuit breakers may not detect it. Additionally, with no
leakage current to ground, residual-current devices also cannot detect the fault.
Series Arcs: Occur when a single conductor or connection is damaged. Localized heating causes the
insulation material to carbonize, allowing part of the current to flow through the carbonized
insulation.
Features
Fast Response: Detects fault arc immediately and transmits the alarm to the monitoring host
Stable & Reliable: Built-in comprehensive electrical equipment database to prevent false alarms
Easy Installation: DIN rail mounted design for simple and convenient installation
Strong An-Interference Capability: Advanced electromagnetic compatibility design ensures high resistance to electromagnetic interference
