Product Description

Product Description

AFDD, Arc-Fault Detection Devices , or being called AFCI, Arc Fault Circuit Interrupter, in North Amerca, in comply wtih IEC/BS EN 62606.
In terms of circuit protection,Timelec has MCB for short-circuit and overload protection, RCD (RCCB) for residual current protection; yet not safe enough. According to statistics, in terms of electrical safety, 90% of fires are caused by electric arc, and we need AFDD for arc protection.

 

Timelec AFCI is AFDCI+RCBO, offering short-circuit, overload, residual current, arc and over-voltage protection, meeting the standard of IEC/BS EN 62606 and IEC/BS EN 61009-1, and it selectively distinguishes a harmless arc from a potentially dangerous arc. For example, it breaks the circuit when it detects electric arc which is a signature of loose connections in home-wiring, as loose connection can develop over time and sometimes become hot enough to cause house fires.

 What are arcs?
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.)

What causes 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. 

Since 2014, IEC 60364 recommends surrounding the installation and application environments of AFDDs in residential and commercial buildings:

•In locations with sleeping accommodations (e.g., hotels, nursing homes, bed-rooms in homes)

•In locations with risks of fire due to high quantities of flammable materials (e.g., barns, wood-working shops, stores of combustible materials)

•In locations with combustible constructional materials (e.g., wooden buildings)

•In fire propagating structures (e.g. high-rise buildings)

•In locations where irreplaceable goods are housed (e.g., museums)

It is recommended that AFDDs be installed at the place of origin of the low voltage final circuit to be protected (i.e., switchboard of an electrical installation ).

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.
