Interruption in Air

The following discussions explain circuit breaker interruption in air, 
including:

• Air-Magnetic Circuit Breakers
• Air-Blast Circuit Breakers

Air-Magnetic 
Circuit Breakers

Figure A.2 and Figure A.3 on page A-4 explain the process that occurs 
for current interruption in an Air-Magnetic Circuit Breaker.

The distinctive feature of Air-Magnetic Circuit Breakers is the use of a 
magnetic field to lengthen the arc and force it into a labyrinth of 
insulating plates where it is stretched, dispersed and cooled by the 
interleaved arc plates.
