Lockheed Martin Select - Arc Circuit Breaker GF-ACFB

Wei Kewei

The LM-100J was first showcased to the world at the 2017 Paris Air Show as the commercial cargo version of the legendary C-130J Super Hercules.

Designed to support civilian transportation needs, it is certified CFR14 Part 25 and must comply with AC25981, which means the wiring of fuel pumps immersed in fuel tanks must be protected from the risk of arcing.

GF-AFCB in circuit breaker panel

There are 14 Crouzet GF AFCBs on each aircraft. Its integrated software has passed DO178 (DAL-B) certification, which means it meets very qualified requirements and has no errors or malfunctions that could lead to major accidents.

Other aircraft using arc protection: Antonov 132, Antonov 158, Antonov 178.

Because standard thermal circuit breakers do not detect ground faults or arcs, this may be the root cause of aircraft disasters.

And the ground fault arc fault circuit breaker sold by Wekewei has a tripping time of only 15 milliseconds, while the time using classical technology is 200 milliseconds, greatly reducing the amount of energy released by the fault.

Can accept the challenge of the latest protection requirements for all electric aircraft.
