BUSS BH-1131 Modular Fuse Block Assemblies

BH-1131 Modular Fuse Block Assemblies are a pair of Bussmann/Eaton modular blocks designed to hold high-speed square-body fuses in 400 A, 2500 V systems. Built on a thermoplastic base with steel-plated mounting studs and nuts, the assembly uses a tin-plated aluminum connector and a spring steel washer, and terminates with a 1/4-20 stud connection to accommodate 6 AWG to 250 kcmil copper conductors. These blocks are intended for solid-state control circuits, VFDs, and UPS applications, providing compact, reliable power distribution in a modular format. Catalog BH-1131 is documented across Eaton’s Bussmann pages and distributor listings (Cooper Electric, Platt Electric, RS-Online), confirming a 400 A rating and a 2500 V rating, with CE, CSA, and UL compatibility notes where applicable.
