Arc Fault Detection Device AFDD-10/2/B/003-A 187168

Arc Fault Detection Device – protecting installations and lives

This two-pole arc fault detection device AFDD-10/2/B/003-A from Eaton is a key element of the fire protection system in any electrical installation. Its task is to detect electric arcs, which can be the cause of fires, before serious consequences occur. The device combines overcurrent and residual current protection functions with an advanced AFDD module, providing comprehensive protection.

Functionality and application

The detector is designed for mounting in electrical distribution boards and protecting circuits against the effects of arcing. The B tripping characteristic makes it well suited for handling impulse loads, such as starting motors or devices with electronic power supplies. The optical signaling of the AFDD module status facilitates diagnostics and a quick response in the event of a failure. The rated residual current of 0.03A provides effective protection against electric shock.

• Early arc detection: Minimizes the risk of fire by identifying dangerous electric arcs.
• Comprehensive protection: Combines overcurrent, residual current and arc fault detection functions in one device.
• Status indication: Built-in optical indicator informs about the correct operation of the AFDD module.
• Versatility: Suitable for use in installations with a voltage of 230V and a frequency of 50Hz.
• Safety: Compliance with overvoltage category III provides protection against voltage surges.

Technical specifications and installation

The AFDD-10/2/B/003-A detector occupies 3 modules in the distribution board, and its installation depth is 67 mm. It has a degree of protection IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. Installation is standard for Eaton modular devices, which facilitates installation and replacement. Energy limitation class 3 ensures adequate resistance to short circuits. The device meets safety standards and has a rated short-circuit breaking capacity of 10kA. Pollution degree 2 indicates the possibility of use in environments with a moderate level of contamination. Sensitivity A ensures optimal performance in typical operating conditions.
