Product Description
The CB3120C is an aircraft circuit breaker designed to interrupt overcurrent and protect wiring and avionics equipment in aircraft electrical systems. This breaker is trip-free per SAE AS58091 standards, meaning it automatically opens when current exceeds its rated amperage, preventing damage to connected loads. Installed on aircraft distribution panels, the CB3120C requires amperage and mounting style selection based on wiring diagrams and aircraft maintenance manual specifications.
Proper installation ensures reliable overcurrent protection across avionics, lighting, and accessory circuits in general aviation and commercial aircraft.
