The A9K23206 is a 2-pole miniature circuit breaker from the Acti9 iK60N series, rated 6 A at 30 °C with a B-curve trip characteristic (magnetic trip between 3 and 5 times In). The thermal-magnetic trip unit handles overloads (thermal bimetal) and short-circuits (solenoid) in one package, so no separate protection relay is needed for the branch circuit. Clip-on mounting to a 36 mm wide DIN-rail profile (4 module pitches at 9 mm each) means it snaps into the same panel footprint as any standard Acti9 or similar MCB.
Deployment context
This is a distribution MCB for AC branch circuits in a final sub-distribution board or consumer unit — think lighting, general-purpose socket outlets, or small motorized loads where the B-curve inrush tolerance is sufficient. The IP20 finger-safe terminals suit enclosed panel installation; the toggle actuator gives local ON/OFF indication and accepts a padlocking device for lockout/tagout during maintenance.
