Arc Fault Detectors – Protecting Installations and Lives

The Eaton AFDD-16/2/B/003 arc fault detector is an advanced device designed to detect electrical arcs in an installation at an early stage. These arcs, often invisible, can be the cause of fires, so their rapid detection is crucial for safety. This two-pole (2P) detector, with a rated current of 16A and a differential current of 0.03A, is designed to operate in installations with a voltage of 230V and a frequency of 50Hz. Its B characteristic ensures appropriate selectivity and minimizes the risk of unnecessary tripping.

Functionality and application

This device is used to protect electrical circuits against the effects of electrical arcs. It is particularly important in places with an increased risk of fire, such as:

• Residential and public buildings
• Industrial facilities
• Warehouses
• Workshops
• Hospitals and educational institutions

Installing the AFDD detector provides an additional layer of protection, complementing traditional overload and short-circuit protection. This minimizes the risk of fire caused by damaged cables or faulty devices.

Construction and parameters

The Eaton AFDD-16/2/B/003 arc fault detector is characterized by a compact design, occupying 3 modules in width. Its IP20 degree of protection provides protection against contact with fingers, which is important from the point of view of safety. Energy limitation class 3 and surge category 3 confirm its resistance to interference and ability to operate in difficult conditions. The rated short-circuit breaking capacity of 10kA guarantees effective disconnection of the circuit in the event of a short circuit. The device operates in AC (alternating current) system, which means it reacts to electrical arcs regardless of polarity. Additionally, the inability to simultaneously disconnect the N pole increases the reliability of the entire system.
