Agency Information:
CE, UL Listed, Std. 248-15, Class T, Guide JDDZ, File E4273
CSA Certified, C22.2 No. 248.15, Class 1422-02, File 53787

Features:
• Small, space-saving fuses provide a high degree of current limitation on short-circuits for excellent component protection
• Commonly applied in electric heat circuits, load center, disconnect switches, and meters
• The small size of the JJN Class T fuses permits installation in panelboards and control centers for system upgrading when existing circuit breakers cannot safely interrupt larger available short-circuit currents
• High speed of response for semiconductor protection
