ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ

What differentiates AFDD-3 from AFDD-1?

AFDD-3 adopts a magnetic tripping mechanism for stable performance under varying loads; AFDD-1 is a standard electronic design. Electrical ratings are otherwise similar.

Does AFDD-3 comply with EN standards?

Yes. It complies with EN62606 (arc fault detection) and EN61009-1 (RCBO).

Which leakage type is detected?

Type A — sinusoidal AC and pulsating DC residual currents.
