Application Fields of E-T-A Aircraft High Performance Circuit Breaker
This type of circuit breaker is highly suitable for overcurrent and short-circuit protection in vehicles and aviation technology, and is an alternative to automatic circuit breakers in measurement, control, and regulation systems.
Application areas of ETA circuit breakers/battery circuit breakers
It is an ideal choice for line protection and main switch of motor vehicles, electric vehicles, ships, airplanes, etc., as well as for load independent remote shutdown of gasoline and diesel vehicles, railway vehicles, and ships.
technology
This series of high-performance circuit breakers has high breaking capacity for thermal tripping or thermal magnetic tripping. Circuit breakers and battery circuit breakers are also based on the principle of thermal magnetic trip. The hot part of the circuit breaker provides delay protection in case of overload. Under high overload and short-circuit current conditions, magnetic components will shut down the faulty circuit within a few milliseconds.
We can provide customer specific designs upon request, such as SG, AP, or CBM types. All circuit breakers in this category provide true electrical isolation.
