  • Provides m otor overload, ground fault and short-circuit protection
  • H elps protect m otors against burnout from overloads
  • H elps protect m otors against burnout from single-phasing on three-phase system s
  • Sim plifies and im proves blackout prevention (selective coordination)
  • Dual-elem ent fuses can be applied in circuits subject to tem porary m otor overloads and surge currents to provide both high perform ance short-circuit and overload protection
  • The overload elem ent provides protection against low level overcurrent of overloads and w ill hold an overload w hich is five tim es greater than the am pere rating of the fuse for a m inim um of ten seconds.
