UL Class Fuses
Littelfuse® POWR-GARD® NLS060 Fast Blow One Time Fuse, 60 A, 600 V AC/400 V DC, 20/50 kA Interrupt, Class: K5, Cartridge Body
NLS series fuses provide low cost protection for general purpose feeder and branch circuits when available short circuit currents are less than 50000 A. They replace all Class H fuses which have only a 10000 A interrupting rating. They are suitable for use in many residential and smaller commercial and industrial applications. NLKP series fuses are Canadian "Code" fuses specifically designed to meet Canadian electrical code type P fuse requirements for residential use. They have a 10000 A interrupting rating. However, to obtain the added benefits of time delay, current limitation and higher interrupting rating, consider the use of POWR-PRO® IDSR Indicator fuses for circuits between 250 and 600 V. The user gets all the benefits of time delay RK5 fuses plus the added benefits of a n indicating fuse that tells when it has opened. complete information on these fuses may be found in the POWR-PRO® section of this catalog. for circuits upto 250 V, see FLNR fuses in this section of the catalog.

SDS Plus 2 cutter drill bits have a strong tapered core to help resist flute breaks, especially when drilling deep holes. For optimal drilling speeds, the two stage flute design features a variable helix pattern that quickly moves debris away from the contact zone. Plus, the two sharp, carbide cutting edges deliver clean, round holes for secure anchor installation. These bits are made in Germany and are GUARANTEED TOUGH® - so tough that we are offering a NO BREAK GUARANTEE. If you have our bits, we have your back.
The IRWIN HANSON Spiral Flute Screw Extractor Set, 6 Piece, features an aggressive left hand design for extra gripping power. Easy out style spiral flutes embed themselves deeper into the metal as the tool is turned so grip increases as resistance increases. With sizes etched onto each tool for quick identification, it includes EX-1, EX-2, EX-3, EX-4, EX-5, and EX-6 extractors.
