Series NB4LE-AFD
NB4LE-AFD arc fault detection circuit-breaker with residual current operated function applies to circuits with a frequency of 50Hz, rated voltage AC 230/240V, 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 increased.
Tripping curve
B curve (I1=1.13In; I2=1.45In; I4=3In; I5=5In) 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 (I1=1.13In; I2=1.45In; I4=5In; I5=10In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
BK curve (I1=1.05In; I2=1.3In; I4=3In; I5=5In) protection and control of the circuits against overloads and short-circuits; protection for people and big length cables in TN and IT systems.
CK curve (I1=1.05In; I2=1.3In; I4=5In; I5=10In)protection and control of the circuit against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
