Cooper Bussmann JJN-60 Class T Fast-acting Fuse 60A

Product Description

The COOPER BUSSMANN JJN-60 is a Class T fast-acting cartridge fuse rated at 60 amps for use in industrial and commercial electrical distribution systems. Measuring 0.563 inches in diameter and 0.875 inches in overall length, this compact fuse delivers high interrupting capacity of 200 kA at AC (RMS) and 20 kA at DC, making it suitable for circuits where fast, reliable overcurrent protection is required. Licensed electricians and electrical maintenance technicians install this fuse in fusible disconnect switches, panelboards, and motor branch circuit applications where Class T fusing is specified.

The JJN-60 is designed for general-purpose overcurrent protection in residential, commercial, and light industrial electrical systems. Class T fuses are commonly specified where space-saving form factors and high interrupting ratings are required in a single device. This fuse is appropriate for use in 60-amp branch circuit and feeder protection applications in fusible switch assemblies and distribution equipment.
