General direct-current protection; extinguish the dangerous arc produced at the moment of interruption.
DC fuses are general protection devices designed for direct-current circuits. With no current zero-crossing in DC, the arc produced at interruption is far harder to extinguish than in AC; the special fuse-element geometry and filler of DC fuses quench this dangerous arc safely.
Available in cylindrical and NH bodies for battery systems, DC switchboards, telecom power supplies, railway systems and industrial DC drives.
