Overview

Mersen PCT30-H is a time-delay midget fuse designed for direct mounting on printed circuit boards, eliminating the need for additional clips or fuseholders. Rated at 500VAC and 30A with a 100kA interrupting rating, this fuse provides robust protection for mainframe power boards, small circuit breakers, and other critical components. Its time-delay feature (12 seconds at 200% rating) accommodates high inrush currents common in lighting, solenoid, motor, and transformer circuits. The double-hole mount design ensures secure attachment to .062 (1.6) nominal circuit board thickness, supporting automated assembly processes and reducing part count for PCB manufacturers. UL Component Recognized under File E60314, the PCT series delivers increased ampere, voltage, and interrupting ratings directly to the board, enhancing reliability and safety in industrial and commercial applications. The PCT30-H is part of Mersen’s PCT series of time-delay, direct-mountable fuses, addressing the need for electrical protection at the PC board as current and voltage requirements increase. These fuses help printed circuit board manufacturers reduce parts by eliminating clips and fuse blocks while allowing automated assembly. The PCT series is UL Component Recognized and suitable for protecting mainframe power boards, small circuit breakers with low interrupting ratings, and other components.
