Extract from Cooper Bussmann datasheet for TJN fuses
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 TJN 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.
No intentional time-delay; opens quickly on overload.
