956A6634G01 is a high-performance aerospace avionics circuit breaker, engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, tailored for overcurrent protection in Airbus A320neo and Boeing 737 MAX flight control and navigation systems during MRO and line operations.

Constructed from a hermetically sealed nickel-plated brass housing with a ceramic arc-extinguishing core, it operates at 28V DC with a 15A rated current and a 2ms trip response time, compatible with 18–22 AWG aerospace wiring. The breaker features a manual reset mechanism, redundant contact design for fault tolerance, and an IP67-rated enclosure. Weighing 0.12 kg and measuring 55mm×35mm×25mm, it functions at -55°C to 125°C. Compliant with FAA Part 25 and EASA CS-25 regulations, it safeguards avionics from overcurrent damage, ensuring uninterrupted power distribution for narrow-body commercial fleets.
