Cooper Industries Bussmann LCL900 Class L Fuse

Cooper Bussmann LCL900 is a non-indicating, time-delay Class L fuse rated for 900 A in 600 V AC circuits, part of Eaton’s Bussmann Edison LCL family. It delivers 200 kA interrupting capacity at 600 V and is UL-listed, designed for use in large distribution switchboards, power panelboards, and heavy industrial equipment where motor inrush and inductive loads require a controlled delay before interruption. The LCL900 features a 2.5-inch diameter body with bolt-on mounting for robust connection to high-current feeders, and is specified for 600 VAC and up to 500 VDC operation depending on system requirements. This model is built to provide current-limiting protection with a time-delay profile that tolerates transient surges while still offering fast fault clearance, helping to coordinate with upstream protection and downstream devices. As part of the Edison Class L lineup, the LCL900 is aimed at industrial environments demanding high-current protection in 600 V-class systems, making it a fitting choice for main feeders to large panelboards, transformer feeders, and other heavy-duty 600 V installations.
