Crouse-Hinds NSB CA3125 Miniature Circuit Breakers (MCBs) are compact overcurrent protection devices used to interrupt current in electrical circuits when overloads or faults occur. The CA3125 designation identifies a specific model within the NSB series of Crouse-Hinds MCBs. These breakers safeguard electrical wiring and components by automatically opening the circuit when current exceeds a safe level.
