Modern detection circuitry and switching transistors make
for durable, reliable and relatively inexpensive circuit breaker
modules from several manufacturers.
If you have electronic circuit breakers on your layout and are
not having any issues, I see no reason to change.
For those of you who are having issues, or designing a new lay-
out, or converting an existing layout to DCC, or have relay style
circuit breakers, or are using bulbs as your primary circuit pro-
tection, I recommend electronic breakers.
I like to divide electronic circuit breakers into three categories:
basic, general purpose and advanced.
