Magnetic circuit breakers utilise an electromagnetic trip mechanism — typically a solenoid-actuated latch — to provide instantaneous overcurrent and short-circuit protection in aircraft DC and AC power distribution systems, with ratings commonly covering 28 V DC and 115 V AC bus architectures and interrupting capacities suited to MIL-SPEC and DO-160 qualification requirements.
