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 3 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
