Littlefuse Inc., the global leader in circuit protection, has unveiled a series of high-voltage Fuse Blocks and Fuse Holders meant for the mechanical installation of fuses. The new series has been developed for applications in the range of 400 to 600 volts. It comprises several fuse mounting alternatives so as to accommodate the mechanical design of the application.
These devices have been optimized for field servicing of such equipment which is either costly to move or for which the downtime is unacceptable. The series of fuse blocks and holders prevents electric shocks while replacing fuses in the field, thus ensuring the safety of the maintenance personnel.
