Features:

  • 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

Features:

  • Provides motor overload, ground fault and short-circuit protection

  • Helps protect motors against burnout from overloads and single-phasing when sized properly

  • 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 on inrush current which is five times greater than the amp rating of the fuse for a minimum of ten seconds
