Abstract
Electrical arc suppression when terminals under load are connected/unconnected is provided via an applied magnetic field causing the arc path to be lengthened, with the consequences that the voltage necessary for the arc to be sustained is increased and the arc energy is decreased. In a preferred form, at least one magnet with a high permeability flux return path is placed adjacent the terminal proximity zone of initial/final touching of mating terminals. The magnetic field increases the arc length, and thereby suppresses the arc by increasing the voltage necessary to sustain the arc and decreasing the energy of the arc.
