The Schneider Electric A9C61210 is a Reflex iC60N integrated control circuit breaker from the Acti9 range — a 10 A, 2-pole, curve B thermal-magnetic MCB with a built-in remote-control coil. It combines overcurrent protection with the ability to switch the load on and off via a pulse, a maintained signal, or a maintained very-low-voltage command, which saves panel space and wiring compared to a separate contactor and breaker.
Rated 10 A with a B curve, so it trips magnetically between 3 and 5 times In — that's 30 to 50 A — making it a good fit for resistive and light inductive loads like contactor coils, control transformers, or small lighting circuits where you want fast fault clearance without nuisance trips from inrush. Breaking capacity is 20 kA Icu at 220–240 V AC and 10 kA Icu at 380–415 V AC, per EN/IEC 60947-2. Control circuit voltage options cover 230 V AC, 24 V AC, 48 V AC, 24 V DC, and 48 V DC, so it adapts to different control schemes without a separate interface relay. The control signal can be a pulse (momentary), a maintained signal, or a maintained very-low-voltage command, giving flexibility for remote or automated switching.
This class of part — an integrated control circuit breaker — is used in control distribution panels where a single device needs to provide both overcurrent protection and remote on/off switching of a load. Typical applications include controlling contactor coils, solenoid valves, small motor starters, or lighting contactors in commercial and industrial power distribution.
