Noark 100004 Ex9BN Miniature Circuit Breaker 1P Curve B 6 A 6 kA
The Noark 100004 is a modular miniature circuit breaker of the Ex9BN series, in a single-pole version with a rated current of 6 A and tripping curve B. It takes up a single DIN module (18 mm) and has a rated breaking capacity Icn of 6 kA according to EN 60898.
It is installed in residential and commercial distribution boards and in photovoltaic combiner boxes to protect a single line against overload (bimetallic thermal release) and short circuit (instantaneous magnetic release), and to isolate the circuit during maintenance work. Curve B, with magnetic tripping between 3 and 5 times the rated current, is the right choice for circuits without high inrush currents — lighting circuits, auxiliary and control circuits, supplies to electronic equipment — and for long lines where the minimum short-circuit current is low. The 6 A rating is typical of auxiliary circuits and lighting circuits.
Key features
Curve B, 6 AMagnetic tripping between 3 and 5 In: the right choice for lighting and auxiliary circuits and for long lines with low fault currents.
6 kA breaking capacityIcn of 6 kA according to EN 60898 and Icu of 10 kA according to IEC 60947-2, suitable for residential and commercial installations.
Limitation class 3Limiting the specific let-through energy reduces the thermal and electrodynamic stress on downstream cables and devices.
Single-module width18 mm wide and 72 mm flush-mounting depth: maximum device density in the board.
Expandable with accessoriesCompatible with auxiliary and signalling contacts, shunt trips, undervoltage and overvoltage releases and residual current blocks.
Dual protectionThe thermal release acts on prolonged overloads, the magnetic one opens instantaneously in the event of a short circuit.
