BUSSMANN JJN-100 Time-Delay Fusible Class T Fuse

The BUSSMANN JJN-100 is a current-limiting, time-delay Class T fuse rated for 100 A and up to 300 V AC (160 V DC), designed for bolted-end mounting in power electronics, motor drives, and other high-current circuits. As part of Eaton’s Bussmann series, this cartridge-style fuse uses bolted-end terminations to withstand high-current fault conditions while tolerating startup surges common in drives and power conversion equipment. The Class T designation denotes a time-delay characteristic that allows brief overloads without immediate interruption, with 300 VAC and 160 VDC ratings defining the maximum safe operating voltages for AC mains and DC bus configurations, enabling use in both AC drive circuits and DC-powered systems. For exact electrical characteristics, mounting details, and compatibility with fuse blocks or holders, refer to the official Bussmann/Eaton catalogs for the JJN-100 to ensure the correct hardware and installation meets applicable standards.
