Arc Fault Detection Device (AFDD)- Information Sheet
Type B & Type C Curve
The PowerBreaker range of combined AFDD/RCBO range are designed and tested for use with
PowerBreaker Consumer Units.
These devices MUST be installed and tested by a qualied electrician in accordance with the
latest Wiring Regulations (BS7671).

INSTALLATION
1. Clip securely on to the din rail making sure the din rail clip at the bottom is pushed in, locking
the AFDD onto the din rail, ensure lever is in the OFF position.
2. Cut & dress wires as per diagram on unit and connect cables as shown in the diagram.

LINE IN
a. ‘Line IN’ terminal connects to the bus bar.
b. Neutral ying lead to the neutral terminal bar (this can be cut to size to suit).
c. Connect the load to the ‘L’OUT and the ‘N’OUT terminals at the top of the AFDD.

3. Before powering up the circuit check all connections are at the correct torque - 2.5Nm.
TESTING
NOTE: Connections to the AFDD do not require to be disconnected if the lever is in the ‘OFF’
position for Insulation Resistance Test (IR test).
To test the AFDD Press the ‘TEST’ button.
When newly tted systems do NOT trip on the TEST button or using the Multifunction Tester (MFT) the
problem is normally caused by an Earth to Neutral fault on the circuit (PME supply).
Installers can easily check the AFDD by removing the LOAD connections on the device and
applying power. If the TEST button works the fault is in the circuit.
RCBO Test
Combined AFDD/RCBOs are manufactured in accordance with IEC 61009-1 and must be tested to
this specication using a calibrated test meter.

TESTING (continued)
AFDD Self-Test function
The combined AFDD-RCBO has a self-test feature which is initiated when the device is switched ON.
• The self-test feature performs a regular test at 1 hour intervals.
• If a self-test failure is detected, the AFDD will trip after 5 seconds.
• When the toggle switch is moved to the ON position, the LED will start ashing 5 times per
second to signal a self-test failure.
TROUBLE SHOOTING FOR END USER
What if the combined AFDD/RCBO Trips:-
1. Reset tripped AFDD/RCBO to ‘ON’ position.
2. If AFDD/RCBO trips again then disconnect all appliances connected to this circuit.
3. Switch AFDD/RCBO to ‘ON’ position and connect 1 appliance at a time to see which
one trips the device.
4. Once faulty appliance has been identied DO NOT USE until it has been checked.
5. Switch AFDD/RCBO to ‘ON’ position.
6. If fault does not clear contact a qualied electrician to check the installation.
