Cooper Bussmann's JJS300 is a small, space-saving, 300 amp, 600 volt AC fuse that provides a high degree of current limitation on short-circuits for excellent component protection. JJS300's are commonly applied in electric heat circuits, load centers, disconnect switches, and meters. The small size of the Cooper Bussmann T-Tron JJS300 fuse permits installation in panelboards and control centers for system upgrading when existing circuit breakers cannot safely interrupt larger available short-circuit currents. JJS300's have a high speed of response for semiconductor protection. The JJS300's are available for printed circuit board applications.
