Selecting circuit protection
Low Voltage, Branch Circuit Rated Fuses
The following fuse selection guides are based on the 2005NEC® and provided fuse recommendations for the variousapplications listed.
These are only suggestions. Final fuse selection should beperformed only by a qualified personnel able to fully assesan application’s circuit protection requirements. If you needassistance in selecting a fuse for a particular application, callthe Cooper Bussmann Application Engineering team. This
team is staffed by degreed electrical engineers and availableby phone for technical and application support Monday –Friday, 8:00 a.m. – 5:00 p.m. Central Time.
Application Engineering can be reached via phone, fax or e-mail:
