Arc Flash Detection Information Center
Arc-flash events are dangerous and potentially fatal to personnel. Arcing and arc-flashes occur when electricity flows across what is normally an insulating medium, producing intense, luminous discharges of electrical energy. Arc-flash detection technology allows circuit-protection devices to operate rapidly to reduce the energy of an arc flash, where most current-detection devices would respond slowly or potentially not at all.
