and short-circuit protection for non-inductive loads. For

applications where short-duration surges and spikes may

cause nuisance fuse opening, consider the use of Littelfuse

Applications

• General purpose circuits with little or no motor load.

• Resistive loads, such as resistance electric heat.

• Loads requiring fast-acting overload protection, such as

equipment containing solid-state devices.
