Connecting blades for sockets of high rupturing capacity (HRC) fuses are manufactured in 3 dimensional versions adapted to various socket sizes for HRC fuses of LV power installations.
The blades have a plastic body (polycarbonate) which includes a brass blade connected with fittings to the copper terminal from the end of the phase cable of short-circuiting devices.
Connecting blades are also provided with a metallic lamella which allows their handling using the HRC fuse extractor (provided with arm protective sleeve) – code MMPS/1-MPR or other models of insulating devices which allow the same type of handling.
