## Long description

Noark Ex9B40J 3P B16 6kA Type B 16A is a three-pole miniature circuit breaker designed for overcurrent protection in residential, commercial and light industrial electrical installations. The device combines a B characteristic tripping curve with a 16 A rated current and a 6 kA prospective short-circuit breaking capacity, enabling reliable interruption of overloads and short circuits on three-phase circuits while maintaining compact dimensions suitable for distribution boards.
Advantages
The Noark Ex9B40J provides selective overcurrent protection with a B-type thermal-magnetic trip characteristic that responds accurately to overloads and moderate short-circuit currents. Its three-pole design ensures simultaneous disconnection of all phases to reduce the risk of phase imbalance and equipment damage. The 6 kA breaking capacity meets common installation requirements and supports safe operation in typical consumer and light commercial electrical systems.
Suitable for
 Protection of three-phase lighting and socket circuits in residential buildings
 Overcurrent protection for small commercial electrical panels
 Motor protection for small motors and pumps with moderate inrush currents
 Distribution board protection in light industrial applications
Key specifications
 Poles: 3 (three-pole)
 Tripping characteristic: B (thermal-magnetic)
 Rated current: 16 A
 Breaking capacity: 6 kA (short-circuit)
 Mounting: DIN-rail compatible miniature circuit breaker form factor
 Application: overcurrent protection for three-phase circuits
How to use
Install the Noark Ex9B40J into a compatible distribution board on a standard DIN rail and connect line and load conductors according to the panel wiring diagram, ensuring correct phase sequence. Verify that the breaker’s rated current and B characteristic match the protected circuit and connected equipment. After installation, operate the device handle to confirm manual switching functionality and test the circuit under controlled conditions before putting the installation into regular service.
Usage recommendations
Select the Noark Ex9B40J where inrush currents are moderate and where a fast response to overloads is required without nuisance tripping from small transient currents. Confirm coordination with upstream and downstream protection devices and follow local electrical codes and installation practices during mounting and commissioning.
