JJN-2 JJN-60 JJN-300 Commonly applied in electric heat circuits, load center, JJN-3 JJN-70 JJN-350 disconnect switches, and meters. JJN-6 JJN-80 JJN-400 The small size of the T-Tron fuses permits installation in JJN-10 JJN-90 JJN-450 panelboards and control centers for system upgrading when JJN-15 JJN-100 JJN-500 existing circuit breakers cannot safely interrupt larger available JJN-20 JJN-110 JJN-600 short-circuit currents. JJN-25 JJN-125 JJN-700 High speed of response for semiconductor protection.
