Product Description

Product Description

Our AFDD, or Arc-Fault Detection Device, synonymous with AFCI (Arc Fault Circuit Interrupter) in the United States, stands as a testament to safety excellence, meeting the rigorous IEC/BS EN 62606 standard. It is a formidable shield for modern electrical systems, providing unmatched protection.
In the dynamic world of circuit protection, Timelec delivers exceptional MCBs to guard against the perils of short-circuits and overloads, while RCCBs offer top-tier residual current protection. Yet, these alone are not enough for total security. Startling figures show that a staggering 90% of electrical fires are due to elusive electric arcs, underscoring the indispensable role of AFDD devices in shielding against such dangerous arc-related incidents.

 

The Timelec AFDD represents a revolutionary fusion of AFDD and RCBO technology, establishing a new standard in protection against short-circuit, overload, residual current, arc, and over-voltage threats. It rigorously complies with the stringent IEC/BS EN 62606 and IEC/BS EN 61009-1 standards, with an expert ability to differentiate harmless arcs from those that present serious danger. Upon detecting an electric arc-a common sign of loose home wiring connections-it quickly disrupts the circuit, preventing the escalation that can lead to devastating house fires.

FAQ

Whatarearcs?
Visible plasma discharges caused by electrical current passing through a normally nonconductive medium, such as air.
It is caused when the electrical current ionizes gases in the air.
The temperature can exceed 600 ºC, sufficient to start a fire.
(20% fire associated with electrical distribution or other electrical appliance faults.)

Whatcauses arcs?
An arc is created when the electrical current jumps between two conductive material. Most 2 types of arcs are Serial
Arc and Parallel Arc.
Most common causes includes:
1. worn contacts in electrical equipment,
2. damage to insulation,
3. break in cable and loose connections, Etc.


What is AFDD?
AFDD is protective device installed in consumer units to provide protection from arc faults.
It uses microprocessor technology to analyze the waveform of the electricity being used to detect any unusual signatures
which would signify an arc on the circuit.
It will cut off the power to the affected circuit and could prevent a fire.

Do I need to install AFDD?
Yes, it is highly recommended where there is an increased risk of fire

According to IEC 60364 - Electrical installations of buildings Part 4-42 :
Arc Fault Detection Devices are designed to limit fire risks caused by the presence of arc fault currents in the final circuits of a fixed installation.They are installed in electrical switchboards, to protect circuits supplying power sockets and lighting and are especially recommended in cases of renovation.

More specifically, the installation of the AFDD is highly recommended to protect circuits with highest risk of fire, such as:

•Protruding cables (risk of knocks)

•Outside cables (greater risk of deterioration)

•Unprotected cables in secluded areas (like storage rooms)

Aging, deteriorating wiring or wiring for which the connection boxes are inaccessible.
