Designed to detect and isolate arcing events, it enhances fire safety and reduces electrical hazard risk.

## Long description

Legrand 415922 is an Arc Fault Detection Device (AFDD) integrated with an LS (overcurrent) switch, designed to detect dangerous arc faults and interrupt the circuit to reduce fire and electrical hazard risks. The unit is intended for installation in standard switchgear and provides combined arc-fault detection and circuit protection for residential and commercial electrical installations.
Advantages
The AFDD with LS switch combines arc detection and overcurrent protection in a single module, saving space in the distribution board. It detects series and parallel arcing events and triggers reliable disconnection to limit ignition risk. Compatibility with standard DIN-rail switchgear and clear fault indication simplify installation and maintenance. The integrated solution reduces the number of devices required in a circuit and provides coordinated protection against both arcs and overloads/short circuits.
Suitable for
 Residential distribution boards
 Commercial and light-industrial electrical installations
 Circuits supplying appliances with risk of insulation degradation
 New installations and upgrades where enhanced fire protection is required
