Fuseholders can be divided into following categories: panel installation fuseholders, PCB installation fuseholers, lead type fuseholders, guide type fuseholders, and car fuseholders. The selection of fuseholders is greatly related to the installation size, suitable fusetube size, its shape and its performance.
