AFDD+ Arc fault detection device

Eaton’s AFDD+ arc fault detection device offers a comprehensive protective solution against fires triggered by arc faults. Through continuous electronic cable monitoring, the device detects arc faults and automatically trips to help prevent electrical fires. At the same time, it conveniently removes the need for three separate protective devices. This all-in-one device combines the protective functions of a residual-current circuit breaker, a miniature circuit breaker, and an arc fault detection device to protect against electrical shock, overcurrent, as well as short circuit or arc fault in power cables.

Safety thanks to preventive arc fault fire protection

Find out how electrical fires occur and how they can be prevented. Eaton has made it its mission to increase public awareness of the dangers posed by electrical power. Find out more!

Core features

  • Protects against arc fault fires, short-circuits, overcurrents and residual currents
  • Saves time during troubleshooting with repetition of the error code
  • In the event of a fault, only the affected final circuit is switched off 
  • Built-in displays indicate the device status and the trip reason
  • User-friendly display of the error code via LED
  • AFDD+ busbar as accessory supports easy and flexible installation

Enhanced protection against electrical ignited fires

The arc fault detection device has been designed primarily for use in private homes but it is also suitable for use in hospitals, retirement and nursing homes etc. In short, any facility with multiple occupants that are difficult to evacuate within a short time span, e.g. shopping malls and airports. Another field of application for arc fault detection devices are buildings that house valuable and flammable objects - such as museums or libraries.

Preventive arc fault fire protection with the AFDD+

Eaton’s AFDD+ detects arc faults using cutting-edge technology in order to protect your home against electrical fires. The device offers enhanced protection against electrical fires and complies with applicable DIN norms. In contrast with other protective devices that are unable to detect arc faults, the AFDD+ reduces the danger posed by arc-fault induced electrical fires.

The danger posed by arc faults

In Europe, more than 25 % of all fires are caused by electrical defects. Conventional protective switchgear protects homes against fires in general, but not against fires ignited by serial and damped parallel arcs, which can occur in any house. Arc faults, and the fires they may trigger, have many possible causes: jammed or damaged cables, pets and rodents who chew through the insulation, loose terminals, damage to the insulation due to nails, screws or UV radiation or antiquated wiring.

Types 

  • Type -A: Protects against AC and pulsating DC residual currents.
  • Type -Li/A: As Type -A, but in addition it is short-time delayed. Highly reliable against unwanted tripping.
  • Type -G/A: 10 ms time delay in order to avoid unwanted nuisance tripping (e.g. during thunderstorms).
  • Type -F: Higher immunity against smooth DC currents and enhanced surge current proof capabilities.

Type F for households and residential homes

Our lifestyle has changed to a more energy efficient behavior. And this is also why your installation needs to adapt to these changes: Energy efficient appliances in your home require the next generation of protection devices. The Type F enables a safe and reliable installation makes your installation ready for the future. High immunity to disturbances caused by energy efficient devices, yet safety above the standard is the benefit for your home.
