The correct answer to this question is C, Operate with a temporary overload. They also provide high performance to protect short circuits. Motor loads and ground faults are also safeguarded with these fuses. With dual element fuses, lower-priced switches can be used.

The switches that are lower priced are often smaller, allowing the user also to save space. Dual fuses are essential because it is vital to protect overcurrents. Regardless of the age of the system, overcurrent devices need to work through short and overload currents. These fuses are essential to ensuring that they do.

Operate with a temporary overload, a time delay-duel element fuse is used to prevent inrush current from blowing the fuse. If a fuse was designed to permanetly operate at a higher current then the fuse would not protect the equipment it was installed for.

The correct answer is3. Operate with a temporary overload. A dual element fuse is designed for dealing with in-rush current IE Starting an electric motor. This type fuse is also known as a time delay fuse and is used in all single and three phase electric motor starters.

Your answer 2, A fuse designed to operate at a higher current, is a fuse with a higher amperage rating.
