Acti9 Miniature Circuit Breakers - MCBs
A Miniature Circuit Breaker (MCB) is an automatic electrical switch designed to protect low-voltage circuits from damage caused by overloads or short circuits. It quickly interrupts power during fault or overload conditions, ensuring the safety and reliability of the electrical network. Thanks to its high sensitivity to current fluctuations, the MCB accurately detects electrical faults. Additionally, when tripped, the OFF position of the switch clearly indicates the faulty section of the circuit, simplifying troubleshooting and maintenance.
