This circuit breaker
has no mechanical parts, except for the reset switch. The power
switching and control components are completely solid state.
It has the added benefit of over- voltage and under-voltage protection.
It will turn off if the input voltage foes too high, protecting
valuable avionics or other equipment.
These circuit breakers
operate differently than conventional circuit breakers in the following
ways:
1. If the circuit
breaker "trips", the switch will remain in the up or
on position, but a red LED will illuminate indicating
2. The electronic circuit
breaker is a three-terminal device. In addition to the usual
two terminals, a ground reference is required fo the electronics
to operate and as a reference for the over voltage and under-voltage
protection.
3. The 14V circuit breakers
will shutdown with an overvoltage of 16V. The 28V circuit breakers
will shutdown with an overvoltage of 33V. The circuit breakers
will also shutdown wit a undervoltage of 10V for the 14V circuit
breaker, or 20V for the 28V circuit breaker.
They are available in 14V & 28V versions,
with the following current levels: 1A, 2A, 5A, 10A.
