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.

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, 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.
