FEATURES

  • Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer
  • Current limitation for non-inductive circuits provides Class T current-limiting response to maximum ground fault and short-circuit conditions
  • 200kA interrupting rating provides high ratings at all circuit locations
  • Small footprint allows more efficient use of available space
  • 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
