NB3LE-AFD
1.1Â 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.
Tripping curve
B curve (3-5 In) protection and control of the circuits against
overloads and short-circuits; protection for people and big
length cables in TN and IT systems.
C curve (5-10 In) protection and control of the circuits
against overloads and short-circuits; protection for resistive and
inductive loads with low inrush current.
