98D71203501002 is a high-reliability aerospace circuit breaker, engineered to AS9100D quality standards and RTCA DO-160G specifications, designed for narrow-body aircraft avionics systems like Boeing 737 MAX and Airbus A320neo. It provides overcurrent and short-circuit protection for critical subsystems—including navigation, communication, and flight control modules—preventing electrical damage during flight and ground operations.

Constructed from flame-retardant aerospace-grade polymer and copper alloy contacts, it features a trip threshold accuracy of ±3%, manual reset functionality, and wide-temperature tolerance (-55°C to 125°C). Weighing 0.08kg with dimensions 45×30×25mm, it fits standard avionics rack mounts. Compliant with FAA Part 25/EASA CS-25, it ensures electrical system stability, reduces avionics downtime, and safeguards flight operational safety for commercial fleets.
