Blade Fuse Bases
A blade fuse base is a carrier that grips the blades of an NH fuse link with its spring contacts and both secures the fuse link to the panel and connects it to the line. It is used in distribution and power factor correction panels to provide a seat for the fuse link on incoming and outgoing lines protected by NH fuses. The Siemens 3NH series lists bases rated 160 A, 250 A, 400 A, 630 A and 1250 A for sizes 000/00, 1, 2, 3 and 4, along with Sigma's NH00 base. Choose the base according to the size of the fuse link to be fitted, its rated current and voltage, the number of poles and the mounting size in the panel. A blade fuse base is not a switching device; where switching on and off under load is required, a fused load break switch is used.
