## Long description

Noark Ex9B40J slim miniature circuit breaker, single-pole (1P) with B10 tripping characteristic and 10 A nominal current is designed to protect electrical circuits from overloads and short circuits in residential and light commercial installations. The compact slim housing allows installation in space-constrained distribution boards and standard DIN-rail mounting, providing reliable overcurrent protection where a small footprint is required.
Advantages
The slim form factor reduces space usage in distribution cabinets while maintaining standard protection functions for single-phase circuits. The B characteristic provides dependable protection for general-purpose circuits and resistive loads with low inrush currents. Mechanical operation and a clear ON/OFF indicator enable straightforward installation and maintenance. Built to common electrical safety standards, the device offers stable tripping behavior for consistent circuit protection.
Suitable for
 Protection of lighting circuits in homes and apartments
 Protection of socket outlets and small appliances
 Use in compact DIN-rail distribution boards with limited space
 Light commercial and office electrical subcircuits
Key specifications
 Poles: single-pole (1P)
 Tripping characteristic: B (B10)
 Rated current: 10 A
 Mounting: DIN-rail compatible slim housing
 Protection type: thermal-magnetic overcurrent protection (overload and short-circuit)
 Manual operation: ON/OFF toggle
How to use
Install the miniature circuit breaker into a compatible DIN-rail distribution board following local electrical regulations and codes. Ensure the breaker is correctly rated for the circuit conductors and loads before connection. Connect the phase conductor to the input terminal and the load conductor to the output terminal, tightening terminals to the specified torque. After wiring, switch the breaker ON and verify continuity and correct functioning with appropriate test equipment. If the breaker trips, identify and rectify the cause of overload or short circuit before resetting.
Usage recommendations
Use this 10 A B-characteristic breaker for general-purpose circuits where low inrush currents are expected, such as lighting and standard socket circuits. Do not use for circuits with high motor or transformer inrush without evaluating an alternative characteristic. Follow national wiring regulations for conductor sizing, terminal torque, and protective coordination.
