Special Features

  • 10 s (minimum) at 500% rated current response time
  • 200 kA at 600 VAC, 20 kA at 300 VDC interrupt rating
  • Considerable cost savings occurs by permitting the use of smaller size switches, panels and fuses
  • 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 1-phase on 3-phase systems
  • Helps protect motors against burnout from overloads
  • Permanent replacement fuse indication
  • Permits the use of smaller and less costly switches
  • Provides a higher deg of short circuit protection (greater current limitation) in circuits in which surge currents or temporary overloads occur
  • Provides motor overload, ground fault and short circuit protection
  • Simplifies and improves blackout prevention (via selective coordination)
  • The overload element provides protection against low level overcurrent of overloads and will hold an overload which is 5 times the amp rating of the fuse for a minimum of 10 s
  • The time delay feature makes it possible to use fuse amp 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
