Littelfuse L15S008 Semiconductor Fuse

Product Description

The LITTELFUSE L15S008 is a semiconductor fuse designed to provide fast-acting overcurrent protection for solid-state devices and power electronics. Semiconductor fuses are engineered to clear fault currents faster than standard fuses, limiting the energy let-through that can damage sensitive components such as SCRs, diodes, and thyristors. This fuse is a purpose-built protective device installed by licensed electricians and industrial maintenance technicians in variable frequency drives, rectifiers, power converters, and related equipment where standard fuses cannot react quickly enough to protect solid-state components.

Semiconductor fuses are used in commercial and industrial electrical systems where power semiconductor devices require current-limiting protection. Typical applications include motor drives, UPS systems, soft starters, and power conditioning equipment. This fuse is suited for installation in panels and assemblies where fast fault clearing is critical to system integrity and equipment longevity.

Key Features

• Fast-acting current-limiting design protects solid-state power devices from damaging fault currents
• Engineered for applications where standard branch-circuit fuses are too slow to protect semiconductors
• Suitable for use in variable frequency drives, rectifiers, and power conversion equipment
• LITTELFUSE manufacture provides consistent quality and dimensional conformance for panel assembly work

Compatibility

Designed as a semiconductor-protection fuse for use in industrial and commercial power electronics assemblies requiring fast-acting current-limiting overcurrent protection.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lockout/tagout the equipment fully before removing or installing fuses. Verify that the replacement fuse matches the voltage rating, current rating, and interrupting rating required by the equipment manufacturer before installation. Do not substitute a standard branch-circuit fuse where a semiconductor fuse is specified.
