NB3LE-AFD

1.1 Function

NB3LE-AFD arc fault detection circuit-breaker with residual current operated function applies to circuits with frequency of 50Hz, rated voltage AC 240V, and rated current up to 32A. It provides overload, short circuit, leakage protection and arc fault detection, and can also be used for infrequent switching of the circuit under normal circumstances.

1.2. Selection
RCD type
Type A – Tripping is ensured for sinusoidal, alternating residual
currents as well as for pulsed DC residual currents, whether
they be quickly applied or slowly increase.
