PC MOUNT FUSES

TIME DELAY FUSES FOR DIRECT MOUNTING ON PRINTED CIRCUIT BOARDS

Ferraz Shawmut’s new PCT series of time-delay, direct-mountable fuses addresses the
increasing need for electrical protection at the PC board as current and voltage require­ments push higher. These fuses help printed circuit board manufacturers reduce parts by
eliminating clips and fuse blocks and allowing automated assembly. PCT fuses can be used
for the protection of main frame power boards, small circuit breakers with low
interrupting ratings and other components. PCT fuses bring protection with time delay,
greatly increased ampere, voltage and interrupting ratings to the board itself and are UL
Component Recognized
