BG CURAFDB20A This BG Fortress 30mA tall body B Curve Type A single pole combined AFDD and RCBO devices offer technology which is extremely effective against fires which may be caused by electrical arc faults and also offeres protection from short circuit, oveload and earth leakage faults
Arc Fault Detection - AFDD's are installed in consumer units as a protection device against arc faults. Arc faults occur when current jumps the gap between two conductive materials. Situations where AFDD's can be installed:
Premises with sleeping accommodation such as houses, hotels and hostels
Locations with a risk of fire due to the nature of processed or stored materials
Fire propagating structures
Locations with endangering of irreplacable goods, for example museums, listed buildings and items with sentimental value
- Detects and disconnects electrical faults that MCB's, RCDs and RCBO's cannot detect, preventing electrical fires
- Combined miniature RCBO
- Voltage: 230V
- Current rating: 20A
- Trip curve: B
- Trip current 30mA
