LED Indication

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

AFDD9NL-40 FAQ

Frequently asked questions about AFDD9NL-40 Arc Fault Detection Device for final distribution and branch circuit protection.

1. What is AFDD9NL-40?

AFDD9NL-40 is an Arc Fault Detection Device assembled from an 18mm-wide double-pole RCBO and an arc-detection module. It is designed for branch circuits to improve electrical safety in final distribution.

2. What protection functions does AFDD9NL-40 provide?

AFDD9NL-40 provides arc-fault protection, leakage (residual current) protection, short-circuit protection, over-current/overload protection, and over-voltage protection.

3. What types of arc faults can AFDD9NL-40 detect?

AFDD9NL-40 offers protection against series arc faults, parallel arc faults, and earth arc faults, helping reduce the risk of electrical fires caused by arcing.

4. Does AFDD9NL-40 also protect against earth leakage faults?

Yes. AFDD9NL-40 integrates RCBO functions, providing leakage protection and a built-in RCD test button to verify residual current operation.

5. What is the rated voltage and frequency of AFDD9NL-40?

AFDD9NL-40 is rated for AC 230/240 V and 50 Hz operation.

6. What rated current options are available?

AFDD9NL-40 is available in 6A, 10A, 16A, 20A, 25A, 32A, and 40A rated current options.
