AFDD9LE-63Y Arc Fault Detection Device (AFDD+RCBO)

General

The AFDD9LE-63Y series Arc Fault Detection Device are assembled by residual current circuit breakers (RCBO) and arc detection modules. The AFDD9LE-63Y 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 overcurrent, short-circuit, leakage or arc-fault occurs in the branch circuits. T key: Test key --- multi-function key · Green light status: running status Press the “T key” and release it quickly(ote that it is the release trigger) to test the breaking functionof the AFDD protector. · Red light flashing state: arc fault alarm stat Pressing the “T key” will immediately cancel the alarm.   Set AFD detection mode:

When the green light is on, keep pressing the “T key” for about 3 seconds, the green light will go out, and it means enteringthe setting state. Press the “T key” again, the green light will fash to indicate the current working mode, and each presswill switch once! There are four working modes: • Flash once: Anti-interference mode • Flashes twice: low sensitivity • Flashes three times: standard mode • Flashes four times: Enhanced mode (not a dedicated scenario, not recommended) The switch wil take efect immediately, Wait for 10 seconds to automatically exit the setting state, or you can long press the”T key” to exitimmediately.

FAQ

1. What is an AFDD RCBO?

An AFDD RCBO is a protective device that combines arc fault detection with overload, short-circuit, and residual current protection. The AFDD9LE-63Y integrates AFDD and RCBO functions in one unit, helping improve circuit safety in branch circuits.

2. What does the AFDD9LE-63Y protect against?

The AFDD9LE-63Y provides protection against series arc faults, parallel arc faults, earth arc faults, earth leakage faults, overloads, and short circuits. This combination helps reduce the risk of electrical fire and improves overall circuit protection.

3. What is the difference between AFDD and RCBO?

An RCBO mainly protects against overload, short circuit, and leakage current, while an AFDD is designed to detect dangerous arc faults that traditional breakers may not recognize. The AFDD9LE-63Y combines both functions for more complete protection.

4. How does an AFDD work?

An AFDD monitors the electrical waveform in real time and identifies abnormal arc characteristics that may indicate a dangerous fault. When a hazardous arc is detected, the device trips quickly to disconnect the circuit and help prevent fire hazards.

5. Where should AFDD RCBO be installed?

AFDD RCBO devices are suitable for branch circuits in residential, commercial, and other low-voltage electrical installations where enhanced fire protection is needed. They are especially useful in areas with higher safety requirements.

6. What current ratings are available for AFDD9LE-63Y?

The AFDD9LE-63Y is available in rated currents of 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, and 63A, making it suitable for a wide range of branch circuit applications.

7. What leakage sensitivity options are available?

The AFDD9LE-63Y offers residual current sensitivity options of 10mA, 30mA, and 100mA. These options allow the device to meet different protection requirements in electrical systems.

8. What tripping curves are available for AFDD9LE-63Y?

The AFDD9LE-63Y is available with B and C instantaneous tripping curves, making it suitable for different load characteristics in low-voltage distribution systems.

9. What standards does AFDD9LE-63Y comply with?

The AFDD9LE-63Y complies with IEC 62606 and IEC 61009-1. These standards cover arc fault detection devices and RCBO performance requirements for electrical protection applications.

10. How do the test button and LED indicator work on AFDD9LE-63Y?

The device includes a multi-function test key and integrated LED indicator. A short press of the test key can perform an arc trip test. The green light indicates running status, while the red flashing state indicates an arc fault alarm. After arc interruption, the reset button must be pressed before the device can be closed again.
