These fuse block designs consist of tin-plated brass terminals. The 520 series fuse blocks provide self-alignment of the clips to the fuse caps. These fuse blocks feature a one-piece clip/terminal and an anti-one-piece clip/terminal design, which assures low contact resistance. The 520 series fuse blocks incorporate 1500V minimum dielectric strength. These fuse blocks come in 5mm × 20mm size. The 520 series fuse blocks feature UL 94V-0 flammability rating and are RoHS compliant.
