3 current-limiting backup fuse Catalog data CA132064EN Attention Eaton is in the process of updating part numbers and technical data due to a material content revision. As a result: All fuses now have new, easier to understand part numbers Some fuses have new dimensions Some fuses have new, more complete s All fuses have new TCCs If you are a new customer considering the fuses for your under-oil, pad-mount overcurrent protection, Eaton recommends you refer to the data in catalog section CA132013EN, or contact your Eaton representative or (877) CPS-INFO for more information. Thank you. The following information pertains to the outgoing part numbers. Refer to catalog section CA132013EN for the most recent part numbers and technical data. If you are a current user of Eaton series fuses, we recommend you convert to the new part numbers listed in catalog section CA132013EN as soon as possible. Please note that your application may need to be re-coordinated to the new fuses. The new TransFusion Coordination program located at can assist you with this task. Or, please contact your Eaton representative or (877) CPS-INFO for more information. 3

4 Catalog data CA132064EN current-limiting backup fuse Fusing equipment General Eaton s Cooper Power series current-limiting backup fuse is used in series with low current primary protection devices such as a Bay-O-Net Fuse or MagneX Interrupter. The fuse is designed for use in oil, Envirotemp FR3 fluid, or an approved equivalent. The fuse s highly efficient currentlimiting section minimizes the effects of high fault current stresses on equipment and the distribution system. Its minimum interrupting is coordinated with that of a low current interrupter to avoid undesirable low current operation; yet its maximum interrupting will clear the highest fault currents likely to occur. Higher continuous current s can be achieved by connecting two fuses in parallel. Application The fuse is used in s to protect and isolate faulted equipment. When connected in series with a low current primary protection device, the 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 or resettable MagneX Interrupter, and it adds the energylimiting protection of a current-limiting fuse. Together, they coordinate easily with upstream and downstream devices. Figure 1. Current-Limiting backup fuse. Installation No special tools are required. The fuse is liquid immersed, mounted as near as possible to the incoming primary bushing to which it is connected. Normal liquid dielectric clearances should be used. Refer to Installation Instructions Sheet MN132001EN for details. Production tests Tests are conducted on 100 percent of production in accordance with Eaton requirements.

Mica spider Provides stable winding support without gene gas and pressure buildup during fuse operation. A B C Solid copper end caps Brass inserts are tapped for attachment of a 1/4 inch - 20 x 1/2 inch lead hardware. Double sealing system Buna-N rubber gasket and epoxy sealant ensures seal performance and integrity. Indelible identification label Easy-to-read voltage and current s and catalog numbers. Fiberglass housing Provides strength and maintains integrity of fuse during any interruption, from minimum melt current to maximum rated current of 50 ka.
