The ARC Fault Detection Device (AFDD) from the DS-ARC1M series is a reliable choice for industrial and commercial applications requiring robust protection against electrical faults. Designed to meet rigorous standards, this device is certified under IEC/EN 62020, ensuring it adheres to international safety and performance benchmarks.
Operating at a rated current of 20 A, the AFDD efficiently handles electrical loads in various settings. It supports a rated voltage of 230/240 VAC with an insulation voltage of 500 V, making it suitable for typical Australian power systems. The device's ability to withstand impulse voltages up to 4 kV further enhances its durability against transient overvoltages.
This single-pole plus neutral (1P+N) unit features a breaking capacity of 10 kA at 230 VAC, providing substantial protection during short-circuit events. Its curve type C characteristic ensures that it can handle moderate inrush currents without unnecessary tripping, which is ideal for environments with fluctuating power demands.
In terms of physical specifications, the AFDD measures 52.5 mm in width, 85 mm in height, and has a depth of 69 mm. Its compact design allows for easy integration into existing setups via DIN rail mounting. The device also offers dual degrees of protection: IP20 when installed inside an enclosure and IP40 when used as intended within panel boards or distribution units.
For installation convenience, the tightening torque is set at 2.8 N-m with a wire stripping length requirement of 12 mm and accommodates cable cross sections up to 25 sq-mm. This flexibility ensures compatibility with standard wiring practices while maintaining secure connections.
Electrical durability is another highlight; the AFDD boasts an impressive lifespan with up to 10,000 operational cycles before needing replacement or maintenance checks—an important factor for cost-conscious operations seeking long-term reliability.
The residual current detection capability is classified as Type A, effectively identifying both AC and pulsating DC residual currents—a critical feature for safeguarding sensitive electronic equipment from potential hazards caused by arc faults.
Finished in RAL 7035 light grey, this device not only meets functional needs but also complements modern electrical panels aesthetically. With its combination of technical prowess and practical design elements tailored specifically towards professional users' requirements across Australia’s diverse sectors—be they industrial plants or commercial buildings—the ARC Fault Detection Device stands out as an essential component within any advanced electrical infrastructure setup.
