Special Purpose Fuses
LA15QS Semiconductor Fuses
150 VAC • Very Fast Acting • 1 – 6000 Amperes
Littelfuse LA15QS series Semiconductor fuses were designed for the
specific protection of diodes and other semiconductor devices rated
150VAC/DC. The LA15QS product line compact design is perfect for
those applications that have limitations on available space.
Features
Low I2t minimizes damage to protected components on short-circuit.
Controlled arc voltage reduces stress to circuit components during
fuse clearing.

•
•
Choice of mounting types provides options for unique termination
requirements.
Indicator options allow identification of blown fuses.
Applications
Protection of heavy duty devices such as electromechanical rectifiers.
