Bussmann JJS-30 Class T Fuse

The Bussmann JJS-30 is a UL-listed Class T fast-acting fuse rated for 30 A and 600 V, belonging to Bussmann's JJS Series (TRON Fast Acting). It is designed to provide rapid interruption of overcurrents in circuits up to 600 VAC, helping protect conductors and connected equipment in industrial and commercial power-distribution and control applications where a Class T device is specified. As a 30 A, 600 V fast-acting fuse in the JJS family, the JJS-30 delivers the quick-clearing performance typical of Class T fuses used in power supplies, motor drives, and protection schemes that require fast fault-clearing response. The Bussmann JJS Series is widely referenced across major distributors and catalogs as the standard 30 A, 600 VAC option within the Class T lineup, reflecting its role as a primary protection component in electrical panels and control systems.
