What is the breaking technique used in Evolis Vacuum circuit breaker.

The breaking technique used in Evolis range is Axial Magnetic Field (AMF).
 
This AMF (Axial Magnetic Field) technique involves applying an axial magnetic field parallel to the axis of the two
contacts which allows a diffuse arc to be maintained even at high current values.
The arc energy is spread over the
whole contact surface area, therefore causing very low levels of erosion.
