Mersen PCT10-H - PCT series of time-delay direct-mountable fuses address the need for electrical protection at the PC board. These fuses help PCB users/manufacturers reduce parts by eliminating clips and/or fuseholders and allowing automated assembly. PCT fuses can be used for the protection of main frame power boards, small circuit breakers with low-interrupting capabilities and other critical components. PCF fuses bring greatly increased ampere, voltage and interrupting ratings to the board itself and are UL Component Recognized.
