The patented Class J power distribution fuse blocks use fewer wire connections to reduce watts loss and overall operating temperature of the panel; while simplifying panel layout. Available in ratings up to 400A; they use up to 65 percent less panel space while lowering inventory costs; and reducing installation time and labor by an average of 33 percent. All blocks are equipped with a fuse clip reinforcing spring to minimize temperature rise while maintaining reliable surface contact between the fuse and clip over the blocks service life.
Available as snap-together one-pole units for toolless assembly of multiple poles at point of use or factory configured 2- and 3-pole units to meet popular stocking requirements. The high 200kASCCR helps achieve a higher assembly short-circuit current rating (SCCR) for compliance with NEC sections 110.10; 409.110(4); 409.22; 440.4(B); 670.3(A)(4) and 670.5. 30A and 60A blocks feature DIN-Rail and panel mount versatility; while 100A to 400A blocks are panel mount. All blocks are available with optional see-through cover to enhance safety with IP20 finger-safe protection; lockout/tag-out capability and open circuit indication. See catalog number tables for details.
