Cooper Bussmann's JJS40 is a small, space-saving, 40 amp, 600 volt AC fuse that provides a high degree of current limitation on short-circuits for excellent component protection. JJS40's are commonly applied in electric heat circuits, load centers, disconnect switches, and meters. The small size of the Cooper Bussmann T-Tron JJS40 fuse permits installation in panelboards and control centers for system upgrading when existing circuit breakers cannot safely interrupt larger available short-circuit currents. JJS40's have a high speed of response for semiconductor protection. The JJS40's are available for printed circuit board applications.
