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 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
