BUSSMANN
BUSSMANN, a brand of Eaton, is a global manufacturer of overcurrent protection components headquartered in St. Louis, Missouri, USA. The brand has been in continuous operation since 1914 and is recognized for its extensive range of fuses, fuse holders, fuse blocks, power distribution blocks, and circuit breakers. BUSSMANN products are specified in industrial, commercial, and automotive applications where reliable circuit protection is required. The product portfolio includes fast-acting and time-delay cylindrical fuses (e.g., LPT, FNA series), semiconductor fuses (e.g., FWA, KAC series), Class L bolt-on fuses (e.g., KLU series), and automotive circuit breakers (e.g., CB222 series). Fuse blocks accommodate glass and ceramic fuses in open-block designs, and power distribution blocks are available with lug terminations for wire sizes from 14 AWG to 2/0 AWG. Voltage ratings span 12 V DC to 600 V AC, with current ratings from 500 mA to 650 A. Many BUSSMANN components carry UL recognition or CSA certification, and the brand is known for standardized dimensions (e.g., 13/32 in x 1 1/2 in midget fuses) that allow direct replacement in existing panels. 3G Electric stocks over 2,160 SKUs of BUSSMANN products, covering fast-acting cylindrical, time-delay, bolt-on, and indicating types, as well as fuse blocks and distribution blocks. This inventory supports maintenance, repair, and operations (MRO) requirements for plant engineers and procurement specialists who need to source specific part numbers for panel upgrades, new installations, or emergency replacements. The range includes both indicating and non-indicating fuses, allowing visual status checks where needed. BUSSMANN’s long history and broad specification coverage make it a common choice for engineers designing or maintaining power distribution systems, motor control centers, and semiconductor protection circuits.
