## Long description

Miniature circuit breaker noark Ex9BN 1P B20 is a single-pole protective device rated for 20 A with B tripping characteristic. Designed for overcurrent and short-circuit protection in residential and light commercial electrical installations, it fits standard DIN-rail panels and provides reliable circuit isolation and protection for lighting circuits, socket outlets and small appliances. The compact housing and standardized mounting ensure compatibility with typical distribution boards and straightforward integration into existing electrical systems.
Advantages
The Ex9BN 1P B20 combines consistent thermal-magnetic tripping behavior with a compact footprint suitable for confined distribution panels. The B trip curve provides sensitivity to moderate inrush currents while protecting wiring and connected equipment from overload and short-circuit faults. Constructed to meet common safety and performance norms for miniature circuit breakers, the device offers clear on/off indication and manual reset capability after fault clearance.

Key specifications
 Poles: single-pole (1P)
 Rated current: 20 A
 Tripping characteristic: B curve (thermal-magnetic)
 Mounting: DIN-rail compatible modular housing
 Function: overcurrent and short-circuit protection with manual reset
 Typical application voltage: compatible with standard low-voltage AC installations
 Operating temperature range: suitable for typical indoor electrical panels
How to use
Install the breaker on a standard DIN-rail inside the distribution board following local wiring regulations. Connect the supply conductor to the line terminal and the protected load conductor to the load terminal, ensuring correct torque on terminals and proper insulation. Use the breaker as the upstream protective device for the intended circuit; switch the breaker off before performing any work on the circuit and reset it manually after a trip only when the fault has been identified and cleared.
Usage recommendations
Select this 20 A B-characteristic breaker where moderate inrush currents occur (for example, incandescent or LED lighting and general-purpose socket circuits) and where protection of wiring is required. Do not use this single-pole device for direct switching of multi-phase loads; follow local electrical codes for group and earth-fault protection. Periodically inspect connections and ensure the distribution board is free of moisture and excessive dust to maintain reliable operation.
