32A 30mA AFDD/RCBO
Type A, B Curve
RCBO with dangerous arc detection 1M 32A B curve 6kA Type A 30mA.
RCBO-AFD in 1 module is a single device consisting of a miniature circuit breaker (MCB) unit and residual current detection (RCD) unit with an integrated Arc fault detection (AFD) unit.
Following the publication of Amendment 2 of the 18th Edition Wiring Regulation on 28th March 2022, the use of Arc Fault Detection Devices (AFDD) have been made mandatory use in certain types of installations:
- Higher Risk Residential Buildings (HRRB)
- Houses in Multiple Occupation (HMO)
- Purpose-Built Student Accommodation (PBSA)
- Care homes
The AFDD mitigates the risk of a fire in the final electrical circuits of a fixed installation due to arcing fault currents, which under certain conditions present a fire ignition risk due to dangerous arc fault.
