What is the choice of low voltage electrical circuit breaker?
At present, some high-performance circuit protection devices provide circuit breakers specifically designed for extreme shock and vibration environments.
n addition, due to the internal locking mechanism of the thermal circuit breaker, it is extremely insensitive to shock and vibration.
For example, a circuit breaker located outside the cockpit is temperature compensated so that its trip characteristics do not change with the temperature fluctuations common in flight.
If a thermal circuit breaker is installed in an environment separate from the protected equipment, the effect of the changing ambient temperature can be corrected by a compensating hot bimetallic sheet.
This feature is often useful when the circuit breaker and the system are exposed to the same heat source. In this case, the protection circuit can track the equipment at higher temperatures for enhanced wiring protection requirements
