CHINT NB4LE-AFD AFDD

1.1 Function

NB4LE-AFD arc fault detection circuit-breaker with residual current operated function applies to circuits with 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 increase.
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.
