Industrial JJN-150 Class T Time-Delay Power Fuse

The Bussmann/JJN-150 Class T fuse (T-Tron) is a 150 A, 300 VAC, very fast-acting, current-limiting power fuse designed for industrial power systems and motor-drive protection, including VFD line protection. It features a 160 Vdc rating with an interrupt capability of 20 kAIC at 160 Vdc and 200 kAIC at 300 Vac, enabling rapid short-circuit clearance while limiting downstream damage. The compact body measures 2.44 inches in length with 0.88 inches in width and height, and uses bolted blade-end connections for secure mounting, with a non-indicating indicator. Rated for 300 VAC / 160 VDC, it carries CE marking and RoHS compliance, aligning with common international standards for electrical protection. Typical applications include protection of power distribution panels and control circuits in industrial environments where fast interruption and current limiting are essential to safeguard equipment and maintain system reliability.
