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 2 Low I t 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.
