## Long description

Miniature slim circuit breaker Noark Ex9B40J 3P B10 is a compact three-pole overcurrent protection device designed for DIN-rail mounting in electrical distribution panels. It provides coordinated protection for three-phase circuits with a B10 trip curve, limiting damage from overloads and short circuits. The slim housing reduces module width on the DIN rail, making it suitable where panel space is limited while maintaining reliable thermal-magnetic protection for residential, commercial and light industrial installations.
Advantages
The Ex9B40J 3-pole B10 breaker combines compact design with a standard thermal-magnetic tripping characteristic, ensuring predictable response to overloads and short-circuit events. Its three-pole configuration enables simultaneous disconnection of all phases for safer maintenance and clearer fault isolation. Designed for DIN-rail mounting, the slim form factor allows higher device density in consumer units and distribution boards. The product is compatible with common accessory fittings and standard installation practices for circuit protection.
Suitable for
Three-phase residential electrical panels and apartments
Small commercial distribution boards and tenant units
Light industrial machinery and motor circuits with moderate inrush currents
Applications where compact DIN-rail protection and simultaneous phase disconnection are required
Key specifications

How to use
Install the circuit breaker on a standard DIN rail in the distribution board following local wiring regulations and the manufacturer's mounting instructions. Connect phase conductors to the top and bottom terminals as indicated, ensuring correct torque on terminal screws. Use the breaker to protect downstream circuits rated for up to 10 A with a type B trip characteristic; verify coordination with upstream protection and connected equipment. Test operation after installation by switching the handle to the ON and OFF positions and perform periodic visual inspections and functional tests according to maintenance schedules.
Использование и рекомендации
The breaker should be selected and installed by qualified personnel. Verify system voltage compatibility and ensure protective coordination with other devices to avoid nuisance tripping and to provide required fault clearance.
