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

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
