AFDD + RCBO combined:
AFDDs will all have automatic test, RCCB included + test button, includes overcurrent and fault current protection.

What buildings will be compulsory.: final socket circuits not exceeding 32A
Higher Risk Residential Buildings (HRRB): over 18M high or 6 stories what ever comes 1st
Houses in Multiple Occupation (HMO)
Purpose built student accommodation
Care homes

The AFDR06 has an LED fault status indicator that operates
a flashing sequence blink code following the reclosing of the device after tripping

No preventative maintenance of the device is required apart from the period pressing of the ‘Test’ button in-line with standard RCD procedure.

The AFDD device will perform internal self-tests periodically in-line with BSEN 62606 device standards.

FuseBox combined AFDD/ RCBO (1P+N) Switched.

Arc Fault Detection Device combined with RCBO (AFDD).

MK SENTRY AFDDs provide protection against fires caused by electrical arcing resulting from faulty wiring or poor connections.
The AFDD analyses curent/voltage characteristics to identify arcing and automically trip to isolate the circuit.
AFDDs detect arcing faults which can be undetected by MCBs and RCDs.

Types of arc fault:

Series arc fault, in-line conductor caused by;

- Loose connections
- Damaged cables (broken, crushed, worn)
- Rodent damage

Parallel arc fault, between live conductors, L-N and L-E undected by MCB/RCD resulting from;

- Damaged insulation
- Pierced insulation (power tools, nails etc)
- Rodent damage
- Poor wiring/damaged appliance plugs

Product Standard: BS EN62606, BS EN61009-1.

Single module, Miniature Bi-Directional AFDD/RCBO combined.

Able to detect Arc Faults.

No miss busbar connection.

Single pole with switched neutral.

Same size as a standard MCB - Can be retofitted into existing boards to upgrade the levels of protection against electrical fires.

What buildings will be compulsory: Final socket circuits not exceeding 32A.
Higher Risk Residential Buildings (HRRB): Over 18M high or 6 stories what ever comes 1st.
Houses in Multiple Occupation (HMO).
Purpose built student accommodation.
Care homes.

Dimensions:
Height: 90mm.
Width: 18mm.
Depth: 77mm.

RCBO with dangerous arc detection 1M 16A 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.
