Features
  • Dual element feature provides the best time delay performance, allowing closer sizing and superior protection of motors and transformers
  • Closer sizing allows for smaller fuses and less costly switches
  • Provides motor overload, ground fault and short circuit protection
  • Helps protect motors against burnout from overloads and single phasing when sized properly
  • 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 time delay feature makes it possible to use fuse amp ratings which are much smaller than those of non-time delay fuses
  • Considerable cost savings occur by permitting the use of smaller size switches, panels and fuses themselves
  • Provides current limitation to help protect downstream components from high fault currents
  • Gives motor running back-up protection to motors without extra costs
  • 200 kA at 600 VAC, 20 kA at 300 VDC interrupt rating
  • 10 s minimum at 500% rated current response time
  • Renewable
