## Summary description

Miniature circuit breaker noark Ex9BN 3P B10 is a 3-pole protection device with B-characteristic tripping and nominal current 10 A. Designed for overload and short-circuit protection in low-voltage electrical installations, it is suitable for residential, commercial and light industrial distribution boards. Compatible with standard DIN-rail mounting and used for selective circuit protection and fault isolation.

## Long description

Miniature circuit breaker noark Ex9BN 3P B10 is a three-pole overcurrent protection device with a B-characteristic trip curve and a rated current of 10 A. It is intended for overload and short-circuit protection in low-voltage electrical installations and fits standard DIN-rail mounting. The breaker provides selective circuit protection and quick fault isolation for distribution boards in residential, commercial and light industrial environments.
Advantages
The device combines three-pole switching with a B-type instantaneous characteristic, ensuring reliable protection of line conductors and connected equipment against moderate inrush currents and short circuits. Compact dimensions and compatibility with standard DIN-rail systems simplify installation and replacement in distribution cabinets. Built for consistent tripping performance, it supports clear fault localization and minimizes downtime in multi-phase circuits.
Suitable for
Protection of lighting and socket circuits in homes and apartments
Distribution boards in small offices and retail premises
Selective protection of motors and small machinery with low inrush currents
Phase-to-phase and three-phase feeder circuits in light industrial installations
Key specifications
Poles: 3-pole design for simultaneous switching and protection of three phases
Tripping characteristic: B curve — suitable for circuits with low to moderate inrush currents
Rated current: 10 A nominal
Protection functions: thermal-magnetic tripping for overload and short-circuit protection
Mounting: compatible with standard DIN-rail (EN/IEC compatible mounting systems)
Application voltage: suitable for low-voltage AC distribution systems (three-phase)
How to use
Install the circuit breaker on a standard DIN-rail inside a suitable distribution enclosure, ensuring correct orientation and secure connection of phase and load conductors. Connect incoming supply lines to the line terminals and outgoing circuits to the load terminals, observing proper tightening torque for terminals and ensuring the unit is installed in a de-energised state. After installation, switch the breaker on to restore the circuit and verify operation by applying normal load conditions. In the event of a trip, isolate the supply before inspecting the protected circuit and reset the breaker only after identifying and rectifying the fault.
Lietošanas ieteikumi
Use the breaker within its rated current and system voltage limits, perform periodic visual inspections and thermal checks of terminal connections, and avoid installing the device in excessively humid or corrosive environments to ensure reliable operation.
