AFDD9RL-63 Arc Fault Detection Device with RCBO Protection

Product Detail

General

The AFDD9RL-63 series Arc Fault Detection Device are assembled by residual current circuit breakers (RCBO) and arc detection modules. The AFDD9RL-63 Arc Fault Detection Device possess the functions of short-circuit protection, overload protection, residual current protection and arc-fault protection. They are suitable for being installed in branch circuits and can quickly cut off the circuits to play a protective role when over current, short-circuit, leakage or arc-fault occurs in the branch circuits.

LED illumination

LED illumination for AFDD operation and arc fault identification 1. LED turns GREEN , AFDD is operating properly 2. LED flashes in RED for 5 times when AFDD is re-closed after tripping, the tripping is caused arc fault. 3. LED turns GREEN when AFDD is reclosed after tripping, the tripping is caused by either overload, short circuit or earth leakage fault. 4. LED flashes in RED, AFDD is operating improperly and shall be replaced by professionals.

FAQ

1. What is an AFDD?

An AFDD (Arc Fault Detection Device) is a protective device designed to detect dangerous electrical arc faults in circuits. When an arc fault is detected, it disconnects the circuit to help prevent electrical fires.

2. What does AFDD9RL-63 protect against?

AFDD9RL-63 provides multiple protections including arc fault protection, residual current (earth leakage) protection, overload protection, and short circuit protection.

3. What is the difference between AFDD and RCBO?

An RCBO protects against overload, short circuit, and earth leakage. An AFDD detects arc faults that may lead to electrical fires. AFDD9RL-63 integrates both AFDD and RCBO functions in one device.

4. Where should AFDD be installed?

AFDD devices are typically installed in final distribution boards to protect branch circuits in residential, commercial, and public buildings where electrical fire risks need to be minimized.

5. Why is arc fault protection important?

Arc faults can be caused by damaged cables, loose connections, or aging wiring. They may generate high temperatures and increase the risk of electrical fires. AFDD devices detect these abnormal arcs and disconnect the circuit quickly.

6. What is the rated current range of AFDD9RL-63?

AFDD9RL-63 is available with rated currents from 6A to 63A, suitable for a wide range of low-voltage distribution applications.

7. What leakage sensitivity options are available?

AFDD9RL-63 supports leakage sensitivities of 10mA, 30mA, and 100mA, depending on the protection requirements of the installation.

8. What tripping curves are available for AFDD9RL-63?

AFDD9RL-63 is available with B and C tripping curves, allowing flexible protection for different load characteristics.

9. What standards does AFDD9RL-63 comply with?

AFDD9RL-63 complies with IEC 62606 (AFDD) and IEC 61009-1 (RCBO).

10. How does the AFDD LED indicator work?

The LED indicates device status. A green light shows normal operation. A red flashing light indicates arc fault detection or abnormal device operation.
