Oil-immersed Current Limited Backup Fuse

• The Current Limited Back Fuse (CL fuse) is used in transformers to protect and isolate faulted equipment.
• When connected in series with a low current primary protection device, such as Bay-O-Net fuse link, the CL fuse becomes an element of a two-part protection system that gives a full range of fault protection.
• This two-part system provides low current protection with the replaceable expulsion fuse.
• Together, the CL fuse coordinates easily with upstream and downstream devices.
