Arc Fault Detection Devices

Why SENTRON arc fault detection devices (AFDD)?

Dangerous arc faults cause many electrical fires, often from minor defects. Our compact SENTRON arc fault detection devices (AFDD) detect faults and immediately disconnect the circuit, preventing electrical fires by quickly and reliably distinguishing dangerous fault arcs through Siemens-patented SIARC technology.

Our arc fault detection devices provide comprehensive electrical system protection by detecting parallel and serial arc faults. In addition, its compact design saves 50% space in distribution boards, allowing for easy replacement of existing circuit breakers.

Protect human life, buildings and valuable assets from fire risk with arc fault detection today.

Key benefits

Enhance fire protection and overall safety

Prevent electrical fires from dangerous arc faults, a common cause of electrical fires. Protect human life, buildings and irreplaceable assets. Achieve early prevention of fire hazards, from the electrical line to the end device.

Ensure comprehensive protection for all buildings

Apply arc fault detection devices in residential, commercial and industrial buildings for new installations and retrofits. Address the higher current load from modern electrical devices in both new and existing structures.

Simplify integration and system modernization

Replace existing miniature circuit breakers (MCBs) or attach to SENTRON MCBs or RCBOs for straightforward integration. Modernize older buildings with advanced protection against electrical fires without needing extra space.

Featured capabilities

Detect and interrupt all types of arc faults

SENTRON arc fault detection devices (AFDD) detect parallel and serial faults and immediately interrupt the circuit, helping to prevent dangerous electrical fires and ensuring all-round protected electrical installation.

Achieve space savings with compact design

Save up to 50% space in your distribution board for new installations with a compact, single modular width design. Replace existing circuit breakers in older buildings to gain advanced protection without extra space.

Utilize patented SIARC detection technology

Use Siemens-patented SIARC technology to measure high-frequency voltage and current noise. Integrated filters and intelligent software analyze signals and quickly disconnect the circuit if abnormalities are detected.
