Features

• Permanent replacement fuse indication
• Provides motor overload, ground fault and short circuit protection
• When used in circuits subject to surge currents such as those caused by motors, transformers and other inductive components, these fuses can be sized close to full load amps to give maximum overcurrent protection
• Permits the use of smaller and less costly switches
• 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 a higher degree of short circuit protection (greater current limitation) in circuits in which surge currents or temporary overloads occur
• Helps protect motors against burnout from overloads
• Gives motor running back-up protection to motors without extra costs
• Helps protect motors against burnout from 1 ph 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 overcurrent of overloads and will hold an overload which is 5X the amp rating of the fuse for a minimum of 10 s
