Why choose it

The NBN113 combines a compact 1-module footprint with a 10 kA breaking capacity, exceeding typical residential requirements. Its B-curve ensures fast magnetic tripping on short circuits while avoiding nuisance trips from inrush currents of lamps and small motors. The clear trip position indicator (red/green) simplifies fault identification.

Ideal use cases

• Protection of socket outlets and lighting circuits in homes and offices
• Distribution boards in apartment buildings and small commercial premises
• Replacement for standard 13 A MCBs in existing installations
