Thermal circuit breakers, some people believe that the first batch of circuit breakers were invented during the time of Thomas Edison.I guess they developed it shortly after the first short circuit occurred.Fuses, circuit breakers, thermal circuit breakersEditor's noteIt is believed that they reached their design peak at some point in the 1930s or 1940s.If we look back at the pictures of the cockpit of World War II aircraft and older commercial planes, the circuit breaker looks exactly the same as it does now.This is one of the problems: the circuit breaker can achieve the expected function, but it has many issues.We believe that the next generation of solid-state circuit breakers has solved most of these problems.

They not only protect circuits and wiring, but also have many other opportunities to improve aircraft.For example, they can measure current.Thermal circuit breakers cannot achieve this.Thermal circuit breakers cannot truly function as switches... but if they do, their lifespan will not be too long.Solid state circuit breakers can replace relays, so you can integrate many control systems into the power distribution system, reduce the weight of the aircraft, remove many wires from the aircraft, and dismantle many unreliable mechanical components that also exist.That's why almost all modern aircraft (designed in the past 5 to 6 years) use solid-state circuit breakers produced by our company or other companies.
