The hazards associated with electrical arc-blasts are well documented. Studies conducted by numerous The same internal racking mechanism was utilized for industries and professional organizations have sought all Magnum DS/SB breakers, regardless of the frame to quantify the intensity of arc-blast, the risks to size.
