Arc Fault Detection Device (AFDD)

Arc Fault Detection Device (AFDDs) represent a critical advancement in electrical safety technology, specifically designed to identify and mitigate the risks associated with arc faults. Unlike traditional Miniature Circuit Breakers (MCBs) or Residual Current Circuit Breakers (RCCBs), AFDDs employ sophisticated electronics to differentiate between normal operating arcs (e.g., in switches or motors) and dangerous, sustained arc faults that can generate intense heat and ignite fires. This proactive detection capability is vital for safeguarding both property and lives.

Our AFDDs are built to meet rigorous international standards, including IEC62606 and IEC60898-1, ensuring reliable performance in demanding environments. They are rated for AC230V and 50Hz systems, featuring a rated impulse withstand voltage (Uimp) of 4kV. With options for B, C, and D tripping curves—corresponding to (3-5)xIn, (5-10)xIn, and (10-20)xIn respectively—our AFDDs can be selected to match specific circuit characteristics and load requirements. Installation is straightforward, utilizing standard DIN-rail mounting, and the devices offer an IP20 degree of protection.

Integrating AFDDs into electrical installations, particularly in high-safety residential circuits and premium commercial setups, significantly elevates protection levels. They are indispensable for electrical consultants, specifiers, and OEM panel builders focused on delivering compliant and secure electrical systems. Beyond our standard offerings, we provide ODM and private label manufacturing support, enabling partners to integrate our high-quality AFDD technology under their own brand.
