Features
  • Provides motor overload, ground fault and short circuit protection
  • Helps protect motors against burnout from overloads, single phasing on 1 ph systems
  • Simplifies and improves blackout prevention (selective co-ordination ratios)
  • 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 over current of overloads and will hold an overload which is five times greater than the ampere rating of the fuse for a minimum of 10 s at 500% of rated current
  • Insulated end caps for 225 to 600 A fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing
  • 200 kA at 250 VAC rms symmetrical, 20 kA at 250 VDC interrupt rating
