Littelfuse Time Delay Fuse

Littelfuse time delay fuses (also called slow-blow or dual-element fuses) protect electrical circuits from damaging overcurrent and short circuits. They are built to tolerate the brief inrush currents common with motors, transformers, and other inductive loads. They open only when an overload is sustained or a short circuit occurs.

Key Features:

• Time delay design that rides through temporary surge currents without nuisance opening
• Dependable overload and short-circuit protection for equipment and wiring
• Cartridge-style construction made for secure fit in standard fuse holders and blocks
• Backed by Littelfuse, a long-established name in circuit protection
• Available in multiple amperage ratings within the product line

Whether you are protecting motor circuits, power distribution, or other equipment with startup surges, Littelfuse time delay fuses help keep systems running reliably while safeguarding components from fault conditions.
