Special Features

  • Considerable cost saving occurs by permitting the use of smaller size switches, panels and fuses themselves
  • Dual element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide both high performance short circuit and overload protection
  • Gives motor running back up protection to motors without extra costs
  • Helps protect motors against burnout from overloads and single phasing when sized properly
  • Provides a good deg of short circuit protection (greater current limitation) to help protect downstream components from high fault currents
  • Provides motor overload, ground fault and short circuit protection
  • Simplifies and improves blackout prevention (selective coordination ratios)
  • The time delay feature makes it possible to use fuse amperage ratings which are much smaller than those of non-time delay fuses
  • When used in circuits subject to surge currents such as those caused by motors, transformers and other inductive components, these fuses can be sized close to full-load amps to give maximum overcurrent protection
