These fuses are recommended for AC power distribution system mains, feeders and branch circuits having inductive loads (motors, transformers) or non-inductive loads (lighting, heating) where the available short circuit current does not exceed 200,000 RMS symmetrical amperes. These "dual element, time-delay fuses have minimum industry standard time-delay of 10 seconds at 5 times the fuse rating (8 sec. minimum for 250V, 30A and less). The time-delay characteristics of these fuses typically allows them to be sized closer to the running ampacity of inductive loads to reduce cost and provide improved over current protection. These fuses will override normal equipment current surges to reduce unnecessary fuse openings. They are the most popular fuses used in the industry and the most economical for most applications, especially motors and transformers. They have moderate current limitation.

Ind Facilities & Factories - Facility: Safety and Security Systems
Non current limiting
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 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 amperage rating of the fuse for a minimum of 10 sec
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
Overload element provides protection against low level over current 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
