OMNI-BLOK® Molded Base Fuse Block for 2AG Fuses RoHS Pb Options: 1. Other colors available on special order. Contact factory. 2. Two different style clips can be supplied for circuit identity or polarization. Contact factory. Compatible Fuses Size 2AG
Description
This low profile Omni-Blok ® Fuse Block design is available with a choice of solder type terminals, Q.C. terminals or P .C. board mountable terminals. The PCB design is offered with either tin-plated brass terminals for normal applications or tin-plated beryllium copper terminals for use in caustic environments. These fuse blocks feature individual barriers which reinforce the fuse clips while providing greater protection against clip damage and electrical shock. The unique design permits self-alignment of clips to fuse cap. This, plus a one-piece clip/terminal assures low contact resistance. Multiple units may be broken apart to obtain desired number of units.
