Dual-element, time-delay fuse – 10 seconds (minimum) at 500% rated amps (8 seconds for 0-30A sizes). Available with indication on select ratings.


  • Provides motor overload, ground fault and short-circuit protection
  • Helps protect motors against burnout from overloads
  • Helps protect motors against burnout from single phasing on three phase systems
  • Simplifies and improves blackout prevention (selective coordination)
  • 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
  • The overload element provides protection against low level overcurrent of overloads and will hold an overload which is five times greater than the ampere rating of the fuse for a minimum of ten seconds.
