The Schneider Electric Acti9 Miniature Circuit Breaker (MCB) is a high-quality protective device engineered to safeguard electrical installations from overload and short-circuit faults. Featuring thermal-magnetic trip technology, the Acti9 MCB disconnects a circuit automatically when current exceeds safe limits, enhancing safety and preventing equipment damage. These breakers are compact and DIN-rail mountable, making them suitable for modern consumer units and distribution boards across homes, offices, and industrial environments.

Acti9 MCBs support a range of current ratings (typically 1 A to 63 A) and trip curves (B, C, D) to suit different load types and inrush conditions. They meet international safety standards such as EN/IEC 60898-1 and EN/IEC 60947-2, ensuring robust performance and compliance. Integrated features like VisiTrip (fault indication) and VisiSafe (safe isolation indication) improve usability and maintenance safety, while IP20 protection and robust design ensure durability and reliable operation in varied conditions.
