Arc erosion characteristics of DC contactor contacts
The arc is generated upon contact breaking-off resulting in surface erosion in the terminals and affecting the performance of electrical contact. As there is no natural zero crossing point in the DC power supply system, the erosion caused by arcs is often more severe in DC contactors than that in AC...
