Bussmann JJN-45 Fuse 45 A

Product Description

The Bussmann JJN-45 is a Class T current-limiting, fast-acting fuse. It provides 10X better current limitation to help prevent equipment damage caused by short-circuit events. With a 200 kA interrupting rating, it complies with NEC Section 110.9 for today's large capacity systems. Its small, space-saving design offers a high degree of current limitation on short-circuits.

• Small footprint allows more efficient use of available space
• Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer
• Current limitation for non-inductive circuits provides class T current limiting response to maximum ground fault and short circuit conditions

Product Highlights

The JJN-45 fuse offers superior component protection with its fast-acting design and high interrupting rating.
