Arc Fault Detection Device (AFDD) - 13/2/B/003-A 187180

Advanced electrical installation fire protection

This two-pole arc fault detection device (AFDD-13/2/B/003-A) from Eaton is a key element of the safety system in every building. Its task is to detect electrical arcs – often invisible causes of fires – before they can lead to serious consequences. The device combines the functions of an overcurrent and residual current circuit breaker with an arc fault detection module (AFDD), providing comprehensive protection.

Functionality and application

The detector is designed for mounting in electrical distribution boards and protecting circuits with a rated current of 13A. The B tripping characteristic makes it particularly recommended for circuits with devices with high inrush current, such as motors or transformers. It detects both series and parallel arcs, increasing the effectiveness of protection. The optical signal of the AFDD module status informs about its correct operation or any failures.

Key features and benefits

• Multifunctionality: Combination of overcurrent, residual current circuit breaker and arc fault detector functions in one device – saving space in the distribution board and simplifying installation.
• Early hazard detection: AFDD detects electrical arcs that can cause fires before they become visible or cause serious damage.
• Status indication: Built-in optical indicator informs about the correct operation of the detector, facilitating diagnostics and maintenance.
• Compliance with standards: The device meets the requirements of overvoltage category III and has a rated short-circuit breaking capacity of 10kA according to EN 61009, guaranteeing safety and reliability.
• Universality: Designed to operate in 230V networks with a frequency of 50Hz.
• Sensitivity A: Ensures high effectiveness in detecting electrical arcs while minimizing the risk of false alarms.
• Compact dimensions: Width of 3 modules allows for easy installation even in tight distribution boards (installation depth 67mm).

The AFDD-13/2/B/003-A detector is an investment in safety that can protect against serious material losses and threats to life. This is particularly important in residential, public and industrial buildings, where the risk of fire is increased. The degree of protection IP20 provides protection against touching with fingers and solid objects larger than 12.5 mm. The device has a pollution degree of 2, which means it is adapted to work in an environment with a moderate level of pollution.
