Acti9 iARC is an AFDD (Arc Fault Detection Device) designed to detect arc faults. It is single-pole + N, with a rated current of up to 25 A. The rated short-circuit capacity (Im) is 500 A. It is suitable for IT systems. The rated short-circuit current (Inc) is 10,000 A, and the (Inc1) for one pole is also 10,000 A according to EN/IEC 62606. Upon detecting a dangerous series or parallel arc fault, the AFDD trips to disconnect the faulty circuit from the power supply. Arc faults can occur due to poor or damaged cable insulation or faulty connections, potentially causing a fire. The two unique VisiTrip indicators of the Acti9 iARC reduce intervention time by showing the tripped circuit and quickly identifying the type of fault. The electrical lifespan is up to 10,000 operations, and the mechanical lifespan is up to 20,000 operations. The rated insulation voltage Ui is 250 VAC. The product can be snapped onto a DIN rail. Its width is 2 TE. Pollution degree 2. Product color is white (RAL 9003). Dimensions are (W) 36 mm x (H) 91 mm x (D) 73 mm. Protection class IP20 (according to IEC/EN 60529) and IP40 when installed in a modular enclosure. This product complies with the EN/IEC 62606 standard.
