Fusible Style Bus Plug

For bus plug systems in power distribution applications, fusible-style bus plugs are among the most critical components for providing overcurrent protection and safe circuit disconnection. Fusible-style bus plugs incorporate fuse protection to safeguard circuits from overloads and short circuits while enabling quick connection and disconnection from busway systems. Electrical.com carries an extensive selection of fusible-style bus plugs from all major manufacturers, including new, used, surplus, and re-certified options. These components are designed to meet the diverse needs of manufacturing facilities, commercial buildings, data centers, and industrial power distribution applications.
